ITEM 1.  DESCRIPTION OF BUSINESS.

Introduction

     Mesa  Laboratories,  Inc.  (hereinafter  referred  to as the  "Company"  or
"Mesa")  was  incorporated  as a Colorado  corporation  on March 26,  1982.  The
Company designs,  develops,  acquires,  manufactures and markets instruments and
systems  utilized in connection with industrial  applications  and  hemodialysis
therapy.  In August 1984, the Company  acquired  Western  Laboratories  Corp., a
manufacturer  and  marketer  of a line of  instruments  for  use in  calibrating
hemodialysis  proportioning  equipment.  In June 1989, the Company  acquired the
DATATRACE(R)product  line of Ball  Corporation.  In February  1993,  the Company
acquired the assets of NUSONICS,  Inc., a manufacturer of ultrasonic flow meters
and analyzers. In December 1999, the Company acquired Automata  Instrumentation,
Inc.,  a  manufacturer  and  marketer  of a  line  of  instruments  for  use  in
calibrating and verifying performance of hemodialysis equipment.

     The Company presently markets the DATATRACE(R)and ELOGG(R)recording systems
which  are used in  various  industrial  applications;  NUSONICS(R)Concentration
Analyzers,  Pipeline Interface  Detectors and Flow Meter products which are used
in  various  industrial  applications;  and two  product  lines  used in  kidney
dialysis [Dialysate Meters and the ECHO Reprocessing  Products].  The Company is
also  performing  research  and  development  to expand the  application  of its
technology.

     All statements  other than  statements of historical  fact included in this
annual  report  regarding  the  Company's  financial  position and operating and
strategic  initiatives and addressing industry  developments are forward-looking
statements.  Where,  in  any  forward-looking  statement,  the  Company,  or its
management,  expresses  an  expectation  or belief as to  future  results,  such
expectation  or  belief  is  expressed  in good  faith  and  believed  to have a
reasonable  basis,  but  there  can  be  no  assurance  that  the  statement  of
expectation or belief will result or be achieved or accomplished.  Factors which
could cause actual results to differ materially from those anticipated,  include
but are not limited to general  economic,  financial  and  business  conditions;
competition  in the data  logging  market;  competition  in the kidney  dialysis
market;  competition in the fluid measurement  market; the discontinuance of the
practice of dialyzer reuse;  the business  abilities and judgement of personnel;
the impacts of unusual  items  resulting  from ongoing  evaluations  of business
strategies; and changes in business strategy.

     Mesa's executive offices are located at 12100 West Sixth Avenue,  Lakewood,
Colorado 80228, telephone (303) 987-8000.

Data Logging

     The world  market for  temperature  sensors,  indicators  and  recorders is
currently  estimated  at over $2 billion and is  projected  to grow at an annual
rate of 4-6% over the next several years. The  electronics-based  thermal sensor
market to which DATATRACE(R)products belong currently exceeds $100 million.

     The  temperature  and  humidity  recording  markets  are highly  segmented.
DATATRACE(R)  products have developed  application  niches within major industry
segments  such  as  food  processing,   medical  sterilization,   pharmaceutical
processing,  transportation,  electronics,  aerospace,  storage  facilities  and
textile  manufacturing.  DATATRACE(R)products  are  used in any  industry  where
temperature,  pressure or humidity  is  critical to the  manufacturing  process,
quality of the  product  or where  product  temperature,  pressure  or  humidity
profiles are required in a continuous or moving process environment.

DATATRACE(R)Micropack Tracers, FRB Tracers and Flatpack Tracers

     The Micropack Tracer utilizes the latest advances in microcircuitry,  power
supply and sensor  technologies.  The  instrument  is computer  based and can be
programmed by the user to take and store  temperature,  temperature and humidity
or temperature and pressure readings.  A lithium battery is utilized so that the
device is completely  self-contained  and requires no external  wires or cables.
The devices  operate at  temperatures  from - 40(0)F to 680(0)F and provide both
high accuracy and  reliability.  Late in March 2002, the Company  introduced its
Micropack  III line of Tracers for  temperature  recording.  The  Micropack  III
offers many new features  including reduced size,  optical data transfer,  wider
temperature  ranges and  increased  data  points.  Currently,  the  Micropack II
Tracers for  temperature  are sold with various  probe  configurations  in three
temperature ranges: LoTemp(R)which records temperatures from -40(0)F to 185(0)F;
Standard  Temp(R),  which  records  temperatures  from  50(0)F to  302(0)F;  and
HiTemp(R),  which  records  temperatures  from 212(0)F to 680(0)F.  The Flatpack
Tracer  provides the customer with a flat profile  instrument in addition to the
round Micropack  Tracer.  The Flatpack Tracer is offered in the same temperature
ranges and probe  configurations  as the  Micropack  Tracer.  Offering  the same
features  but  slightly  larger  than the  Micropack  II Tracer,  the FRB Tracer
provides users with the ability to replace batteries at their facility, lowering
operating cost and down time for factory  replacement of the battery.  Utilizing
the same electronics and FRB Tracer packaging, the Company offers a humidity and
temperature  version of its FRB Tracer  product and a pressure  and  temperature
version  of its FRB  Tracer  product.  At the end of fiscal  2004,  the  Company
introduced  the  humidity and pressure  versions of its  Micropack  III Tracers,
which will offer the product's  users  reduced  size,  optical data transfer and
increased data points. In early fiscal 2005, the Company began introduction of a
4-20 mA (milliamp)  Tracer.  This user scalable logging device is completely new
and will allow users to log the 4-20 mA output of various fixed monitors  within
the user's  process and correlate that data to the product data collected by our
loggers.  In this way, the user may bring  additional data parameters into their
analysis without  compromising data integrity as required by various  regulatory
bodies.

     The  DATATRACE(R)Tracers  can be placed  completely  inside a container  or
process to provide true time and temperature or time,  temperature and humidity,
or  time,   temperature  and  pressure  profiles  of  manufacturing   processes,
transportation systems and storage facilities. Optional probe configurations and
attachments  allow the Tracers to be adapted to a wide variety of  applications.
By  eliminating  the need for wires or cable  connections,  the  Tracer  greatly
reduces set up time while increasing measurement reliability.

DATATRACE(R)PC Interface

     The DATATRACE(R)product  line also includes PC Interface Modules and system
software for user  programming of the Tracer  instruments and data retrieval for
graphics  software  and  displaying  and  analyzing  results.   Programming  and
retrieval of data from the Tracer is achieved by placing the  instrument  in the
PC  Interface  Module  which is  linked to a  personal  computer.  The  system's
software is menu driven,  allowing  the  operator to quickly and easily  program
start  time  and  date,  sample  intervals  and  run  ID.   Programming  can  be
accomplished  within fifteen seconds by the operator.  After a process run, data
is retrieved by returning  the Tracer to the PC Interface  Module and  following
the menu instructions.

ELOGG(R)Dataloggers

     The  Company  distributes  the  ELOGG(R)Datalogger  product  line in  North
America.  The  ELOGG(R)line  is  similar  in  concept  to the  DATATRACE(R)line,
featuring  different  benefits  to the  end-user  such as longer  battery  life,
extended   memory  and   humidity   logging  in  certain   models.   Unlike  the
DATATRACE(R)products,   the   ELOGG(R)is  a  larger   device  which  is  not  as
environmentally  resistant  and  is  ideally  suited  for  long-term  monitoring
applications,  such as  transportation  and warehousing.  The ELOGG(R)line  also
features a PC Interface Module and software for user programming.

Sonic Fluid Measurement

     The Company's  sonic fluid  measurement  product line consists of two major
components: Sonic Flow Meters and Concentration Monitors. While the total market
for flow  meters is very  large,  the  NUSONICS(R)Sonic  Flow  Meters best serve
applications  where  cleanliness,  resistance to corrosives or  portability  are
required.  Specific applications where the  NUSONICS(R)products are particularly
well  suited  include  water   treatment,   chemical   processing  and  heating,
ventilation and air conditioning (HVAC) applications.

     The  Concentration  Monitor  component  of the  product  line  consists  of
Pipeline Interface Detectors and Concentration Analyzers. The Pipeline Interface
Detector serves a smaller market niche while the Concentration Analyzers serve a
wider variety of industry application,  such as chemical,  food,  pharmaceutical
and polymerization processes.

NUSONICS(R)Sonic Flow Meters

     The Sonic  Flow  Meter  line is a range of  products  which  are  suited to
various fluid measurement applications.  The Model CM800 Sonic Flow Meter is the
Company's  main  wetted  transducer  meter.  With  transducers  that are mounted
through the pipe wall and in contact with the material flowing through the pipe,
it is the most accurate type of ultrasonic  flow meter.  The Model 90 Sonic Flow
Meter features  strap-on  transducers  and is sold in portable and fixed process
versions. This product offers flexibility and portability for measuring flow and
is totally noninvasive, measuring flow rates through the pipe wall. In addition,
the  Company  markets  doppler  flow  meters  in  both  permanent  and  strap-on
transducer models.  Unlike the transit-time  technology that the Company's other
flow products utilize to measure clean fluids with dissolved solids, the doppler
technology is utilized when the fluids to be measured  contain either  suspended
solids or entrained  gases.  Over the past five years, the ultrasonic flow meter
market has shifted preference to strap-on  transducer flow meters and has become
highly price  competitive.  While the Company  continues to sell its flow meters
for certain  applications,  demand for this product line has  contracted and the
contribution  of this  product  line  has  declined  to less  than  10% of total
revenues in fiscal 2004.

NUSONICS(R)Sonic Concentration Analyzers

     Liquid composition can be determined by measuring sound velocity. Since the
sound velocity of any liquid is unique, the relationship between sound velocity,
liquid  composition  and  temperature  is different for every  liquid.  Once the
relationship  is known,  sound velocity can be used to monitor changes in liquid
composition,  often with much greater  precision than can be realized with other
measuring devices.

     Composition  Analyzers  are  marketed to various  industrial  users and are
currently  used to monitor  more than 250  different  materials.  On a real time
basis,  the analyzer  will  monitor the  composition  of  materials  for process
control of blending  operations  or for tracking the progress of  polymerization
processes.   The  CP20  Analyzer  is  the  Company's  newest  analyzer  product.
Incorporating  state-of-the-art  electronic design and a new transducer  design,
this product offers advanced features,  smaller size, reduced manufacturing cost
and simpler installation.  In addition, the Company also offers its Model 86 and
Model 87 (a laboratory model) Composition Meters.

     Based on the same technology as the Composition Analyzers, the Company also
markets Pipeline Interface  Detectors to the petroleum  pipeline industry.  This
instrument is used to monitor the interface of similar  materials in a pipeline,
such as different  grades of unleaded fuel. By detecting these  interfaces,  the
pipeline  operator  can  accurately  perform  switching  operations  within  the
pipeline system.

Kidney Hemodialysis Treatment

     Patients with kidney failure  (known as end stage renal  disease,  or ESRD)
require the removal of toxic waste products and excess water through  artificial
means.  This  process is  generally  performed  three times per week and is most
often accomplished through the use of hemodialysis.

     Hemodialysis  requires the treatment to be conducted on a dialysis  machine
through the use of a disposable cartridge known as a dialyzer.  Blood is brought
extracorporally  to the dialysis  machine for control and  monitoring and passes
through the dialyzer  where waste  products  and excess water are removed.  This
treatment  generally  lasts three to four hours and is conducted three times per
week. These  hemodialysis  procedures are performed in kidney dialysis  centers,
hospitals  and in the home.  The bulk of the  treatments  are  conducted in over
3,500 clinics and hospital centers.  Currently,  there are over 275,000 patients
in the U.S. undergoing dialysis therapy.

     In addition to the  reimbursement  policies of the United States Government
and state  agencies,  the Company's  revenues from its dialysis  products can be
expected to be dependent  upon the policies of  insurance  companies  and kidney
foundations.

Dialysate Meters

     Mesa's  Dialysate  Meters  are  instruments  that are used to test  various
parameters of the dialysis fluid (dialysate).  Each measures some combination of
temperature,  pressure, pH and conductivity to ensure that the dialysate has the
proper  constituency to promote the transfer of waste products from the blood to
the dialysate. The meters are used to check the conductivity and other variables
of the  dialysate  before the  dialysis  process  begins.  The meters  provide a
digital  readout that the patient,  physician or technician  uses to verify that
the dialysis unit is working within prescribed limits.

     The Company's  Western Meter product,  Model 90DX,  measures  conductivity,
temperature,  pressure and pH. Model 90DX is  microprocessor-based  and features
improved accuracy and user convenience and field calibration capabilities.

     In December 1999, the Company acquired Automata  Instrumentation,  Inc. and
its line of Dialysate Meters. This line features the NEO-2, Phoenix,  Neo-Stat +
and Hydra  meters.  The NEO-2  Meter,  introduced  in  October  1999,  is a next
generation   meter  that  replaces  the  Company's   NEO-1  Meter  and  measures
conductivity,  pressure,  temperature  and pH. The remaining  meters are smaller
sample meters  utilizing a patented,  simple and unique syringe sampling system.
With its ease of  operation  and lower  cost,  this  group of meters is  usually
utilized by the patient care staff of hemodialysis facilities.

The ECHO MM-1000 Dialyzer Reprocessor

     Dialyzer  reuse is a procedure  in which a  patient's  dialyzer is cleaned,
performance tested and disinfected before it is reused by the same patient.  The
approximate  cost  of  the  dialyzer  is  $10-$40,  and  each  patient  requires
approximately 156 dialyzers annually if no reuse is employed.

     The ECHO MM-1000 Dialyzer  Reprocessor is a fully automated  dialyzer reuse
machine for which the Company received permission to market from the FDA in June
1982. It  automatically  cleans,  rinses,  tests and delivers  disinfectants  to
dialyzers after dialysis therapy, thereby allowing the dialyzer cartridges to be
reused  rather than  disposed  of after each use. It is designed to  accommodate
virtually all manual reprocessing  procedures in use today and can be programmed
to automate them without  extensive  modification or rework.  Manual  procedures
have been used to reprocess dialyzers  effectively for over 30 years and are the
basis of most automated  systems in use today.  Additionally,  the system can be
programmed   to  use   prescribed   chemicals.   The  ECHO   System  is  totally
self-contained,   aside  from  water  and   chemicals,   and  requires  no  user
adjustments.

The Reuse Data Management (RDM) System

     The Company  markets its Reuse Data  Management  (RDM)  System.  The system
consists of a custom database  management  software  package,  computer  system,
barcode scanner and label printer. The RDM System is stand alone, and is capable
of  operating  with any reuse  method  whether  automated  or manual.  Utilizing
barcode technology,  the RDM System automates much of the data entry involved in
the record keeping  process of managing  reuse,  and will provide record keeping
and reporting to satisfy both patient management and regulatory requirements.

Manufacturing

     The  Company  assembles  its  manufactured  products  at  its  facility  in
Lakewood, Colorado. The Company's manufacturing consists primarily of assembling
and testing materials and component parts purchased from others.

     Most of the materials and  components  used in the Company's  product lines
are available from a number of different  suppliers.  Mesa  generally  maintains
multiple  sources of supplies for most items but is dependent on a single source
for certain items. Mesa believes that alternative sources could be developed, if
required,  for present single supply sources.  Although the Company's dependence
on these single supply  sources may involve a degree of risk, to date,  Mesa has
been able to acquire sufficient stock to meet its production schedules.

Marketing and Distribution

     The Company's  domestic sales of its dialysis products are generated by its
in-house  marketing  staff  while  the  Company  maintains  an  organization  of
independent  manufacturers'  representatives  to distribute its  DATATRACE(R)and
ELOGG(R)product   lines.   For  its   NUSONICS(R)   product  lines,  a  separate
organization  of  manufacturers'  representatives  is maintained.  International
sales are conducted  through over 50 distributors.  During the fiscal year ended
March 31, 2004,  approximately 72% of sales have been domestic and 28% have been
international to countries throughout Europe, Africa,  Australia, Asia and South
America, as well as Canada and Mexico.

     Sales promotions include attendance by Mesa representatives at conventions,
the  continuation  of direct mail  campaigns  and trade journal  advertising  in
industry related publications.

     Customers of Mesa's dialysis  products  primarily  include dialysis centers
and dialysis  equipment  manufacturers.  The primary  emphasis of the  Company's
marketing  effort is to offer quality  products to the  healthcare  market which
will aid in cost containment and improved patient well-being.

     DATATRACE(R)and  ELOGG(R)customers  include  numerous  industrial users who
utilize  the  products  within a variety of  manufacturing,  transportation  and
storage applications. The emphasis of the Company's marketing effort is to offer
a quality  product that  provides a unique and flexible  solution to  monitoring
temperature,  pressure  or humidity  without  interfering  with the  processing,
transportation or storage of the product.

     NUSONICS(R)customers  include various  industries such as water  treatment,
manufacturing,   HVAC  and  petroleum  product  transportation.   The  Company's
marketing  efforts are focused on offering flow  measurement  and  concentration
monitoring in difficult environments where noninvasive monitoring techniques are
required.

     During the fiscal  year ended  March 31,  2004,  one  customer  represented
approximately  12%  of  the  Company's  revenues  and  approximately  11% of the
Company's accounts  receivable  balance.  During the fiscal year ended March 31,
2003 one customer  represented  approximately 11% of the Company's  revenues and
approximately 6% of the Company's account receivable balances.

Competition

     Mesa competes with major medical and instrumentation companies as well as a
number  of  smaller  companies,  many  of  which  are  well  established,   with
substantially  greater  capital  resources and larger  research and  development
facilities.  Furthermore,  many of these  companies have an established  product
line and a significant operating history.  Accordingly,  the Company may be at a
competitive  disadvantage  due to such  factors  as its  limited  resources  and
limited marketing and distribution network.

     Companies with which Mesa's medical products compete include Cantel Medical
Corporation. Companies with which Mesa's DATATRACE(R)and ELOGG(R)instrumentation
products compete include GE Kaye,  Ellab and Orion.  Companies with which Mesa's
NUSONICS(R)products  compete include Controlotron,  Badger Meter, Rosemount, and
GE Panametrics.

     In the area of dialyzer reuse, management believes that the availability of
an  automated   reprocessing  system  which  consistently  cleans,   rinses  and
disinfects dialyzers,  as well as tests them for physical performance and leaks,
can dramatically alter the reuse patterns.  Mesa believes that it is the largest
supplier of meters used to calibrate hemodialysis equipment, although it has not
conducted independent market surveys. The DATATRACE(R)and ELOGG(R)products offer
unique  solutions  to  monitoring  temperature  or humidity and  temperature  or
pressure   and   temperature   through  a   continuous   process  or   long-term
transportation and warehousing applications.  Although there are other solutions
to   temperature,    humidity   and   pressure   monitoring    available,    the
DATATRACE(R)products  offer  a  miniaturized,  self-contained,   environmentally
resistant, wireless solution.  NUSONICS(R)products offer solutions to monitoring
of  clean  fluids  as well as  highly  corrosive  materials,  which  are  either
noninvasive  or do not  disturb  the  flow  of the  product  through  the  pipe.
NUSONICS(R)products  also offer a unique solution to monitoring  variations in a
fluid's  concentration  as the fluid passes  through a pipeline into or out of a
process.

Government Regulation

     Medical  devices  marketed  by Mesa are  subject to the  provisions  of the
Federal Food, Drug and Cosmetic Act, as amended by the Medical Device Amendments
of 1976  (hereinafter  referred to as the "Act"). A medical device which was not
marketed prior to May 28, 1976, or is not  substantially  equivalent to a device
marketed  prior to that date,  may not be marketed  until  certain data is filed
with the FDA and the FDA has  affirmatively  determined that such data justifies
marketing under conditions  specified by the FDA. A medical device is defined by
the Act as an  instrument  which (1) is intended for use in the diagnosis or the
treatment of disease,  or is intended to affect the structure of any function of
the human body;  (2) does not  achieve its  intended  purpose  through  chemical
action;  and (3) is not dependent upon being  metabolized for the achievement of
its principal intended purpose. The Act requires any company proposing to market
a medical  device to notify the FDA of its intention at least ninety days before
doing so, and in such  notification must advise the FDA as to whether the device
is  substantially  equivalent to a device  marketed prior to May 28, 1976. As of
the date hereof, the Company has received  permission from the FDA to market all
of its medical products.

     Mesa's medical  products are subject to FDA  regulations  and  inspections,
which may be time-consuming and costly.  This includes on-going  compliance with
the FDA's current Good Manufacturing  Practices regulations which require, among
other things,  the systematic  control of manufacture,  packaging and storage of
products  intended for human use. Failure to comply with these practices renders
the product  adulterated  and could  subject the Company to an  interruption  of
manufacture and sale of its medical products and possible  regulatory  action by
the FDA.

     The  manufacture  and sale of  medical  devices is also  regulated  by some
states.  Although there is substantial overlap between state regulations and the
regulations  of the FDA,  some  state laws may apply.  Mesa,  however,  does not
anticipate  that complying with state  regulations  will create any  significant
problems.  Foreign  countries also have laws regulating  medical devices sold in
those  countries,   which  may  cause  us  to  expend  additional  resources  on
compliance.

Employees

     At March 31,  2004,  the Company had a total of 49  employees,  of which 48
were full-time  employees.  Currently,  nine persons are employed for marketing,
four for research and development,  29 for  manufacturing  and quality assurance
and seven for administration.

Additional Information

     For the fiscal years ended March 31, 2004 and 2003, Mesa spent $331,740 and
$259,966,   respectively,   on   Company-sponsored   research  and   development
activities.

     Compliance with federal, state and local provisions which have been enacted
regarding the discharge of materials into the environment or otherwise  relating
to the protection of the  environment  has not had, and is not expected to have,
any  adverse  effect upon  capital  expenditures,  earnings  or the  competitive
position of the  Company.  Mesa is not  presently a party to any  litigation  or
administrative   proceedings   with   respect  to  its   compliance   with  such
environmental  standards.  In addition,  the Company does not  anticipate  being
required  to  expend  any  significant  capital  funds  in the near  future  for
environmental protection in connection with its operations.

     The  Company  has  been  issued  patents  for  its  DATATRACE(R)temperature
recording devices, its NUSONICS(R)sonic flow measurement and sonic concentration
monitoring  products and its Automata dialysis meters.  Failure to obtain patent
protection on the Company's remaining products may have a substantially  adverse
effect upon the Company  since there can be no  assurance  that other  companies
will not  develop  functionally  similar  products,  placing  the  Company  at a
competitive  disadvantage.  Further,  there  can  be no  assurance  that  patent
protection will afford protection against  competitors with similar  inventions,
nor can  there be any  assurance  that the  patents  will  not be  infringed  or
designed around by others. Moreover, it may be costly to pursue and to prosecute
patent  infringement  actions against  others,  and such actions could interfere
with the business of the Company.

ITEM 6. MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.

Overview

     Mesa Laboratories, Inc. manufactures and distributes electronic measurement
systems  for  various  niche  applications,   including  renal  treatment,  food
processing,   medical   sterilization,   pharmaceutical   processing  and  other
industrial  applications.  Our Company  follows a philosophy of  manufacturing a
high quality  product and  providing a high level of on-going  service for those
products.  In order to optimize the  performance of our Company and to build the
value of the Company for its  shareholders,  we continually  follow the trend of
various key  financial  indicators.  A sample of some of the most  important  of
these indicators is presented in the following table.

(1)  Average  return on  stockholder  investment is calculated by dividing total
     net  income  by the  average  of end of year and  beginning  of year  total
     stockholder's equity.

(2)  Average  return on  invested  capital  (invested  capital = total  assets -
     current  liabilities - cash and short - term  investments) is calculated by
     dividing  total net income by the average of end of year and  beginning  of
     year invested capital.

     While we continually  try to optimize the overall  performance  and trends,
the table above does highlight various exceptions.  These exceptions are usually
influenced  by a more  important  need. A review of the table above shows a very
high Trade  Receivables  balance and high Days Sales Outstanding in fiscal 2001.
At the time that these indicators were showing below average performance, we had
recently  completed the acquisition of Automata  Instruments,  Inc., and a large
amount of our  administrative  resources were being focused on  improvements  to
systems, work flows and new customer satisfaction.  Similarly, the Current Ratio
in fiscal 2001 was nearly one half of historical levels, and reflected the lower
liquidity of the Company following the acquisition of Automata Instruments, Inc.

Results of Operations

Net Sales

     Net sales for fiscal 2004 increased less than one percent from fiscal 2003,
and net sales for fiscal 2003  increased less than one percent from fiscal 2002.
In real dollars,  net sales of $9,126,000 in fiscal 2004 increased  $44,000 from
$9,082,000 in 2003, and net sales of $9,082,000 in fiscal 2003 increased $38,000
from $9,044,000 in 2002.

     Our revenues come from two main sources, which include product revenues and
parts and service revenues. Parts and service revenues are derived from on-going
repair and recalibration or certification of our products.  The certification or
recalibration  of product  is  usually a key  component  of the  customer's  own
quality system and many of our customers operate in regulated  industries,  such
as food processing or medical and  pharmaceutical  processing.  For this reason,
these revenues tend to be fairly stable and grow slowly over time. During fiscal
years  2004,  2003 and  2002 our  Company  had  parts  and  service  revenue  of
$2,644,000,  $2,511,000 and $2,238,000.  As a percentage of total revenue, parts
and service revenues were 29% in 2004, 28% in 2003 and 25% in 2002.

     The  performance  of new product  sales is  dependent  on several  factors,
including general economic  conditions in the United States and abroad,  capital
spending trends and the  introduction of new products.  Over the past two fiscal
years,  general  economic  conditions  have been  starting to improve,  and more
recently,  capital spending has also begun to improve.  New products released to
the market over the past two fiscal years  include the  Datatrace  Micropack III
temperature loggers during the middle of fiscal 2003 and the Datatrace Micropack
III humidity and pressure loggers at the end of fiscal 2004. Introduction of the
humidity  and  pressure  loggers came too late in fiscal 2004 to have much of an
influence on revenues.  All three loggers,  temperature,  humidity and pressure,
utilize a common PC Interface system and operating software. For this reason, we
believe that some  customer  purchasing  decisions  were  probably  delayed into
fiscal  2005,  as those  customers  awaited  introduction  of the  humidity  and
pressure  loggers.  For fiscal years 2004,  2003 and 2002 product  sales for our
company were $6,482,000, $6,571,000 and $6,806,000.

     Over fiscal 2004, our medical products  increased four percent for the year
compared to the prior period. The major share of this increase was due to higher
sales  of our  meter  products  and  accessories,  and an  increase  in  service
revenues.  Sales of the company's dialyzer reprocessing products declined during
the year as the trend  toward  usage of single use  dialyzers  continued  in the
domestic  market  place.  A high  percentage  of our  reprocessor  revenues  are
generated  from  foreign  markets  and it is not  expected  that this trend will
continue to have an  appreciable  negative  effect on future  sales.  Currently,
research and  development  efforts are in process to further enhance our line of
hand-held dialysate meters.

     During fiscal 2004, sales of the Datatrace brand of products declined after
the increases  reported in the prior year. For the year,  sales  decreased seven
percent  compared to the prior year. At the end of the quarter,  we released our
latest  version of user software and shipped  initial units of the Micropack III
humidity  and  pressure  loggers to  customers.  These new  products  will allow
customers  who measure more than one  parameter in their  process to program and
retrieve  data from the same PC Interface  device.  During April the company has
begun  introduction of its new 4-20 milliamp logger.  This user scalable logging
device is completely new and will allow users to log the 4-20 milliamp output of
various  fixed  monitors  within their  process and  correlate  that data to the
product data collected by our loggers. In this way the user may bring additional
data  parameters  into their  analysis  without  compromising  data integrity as
required by various regulatory bodies.

     During  fiscal  2004,  sales  of the  Nusonics  line  of  ultrasonic  fluid
measurement  systems increased by 27 percent.  This is the first annual increase
for these products in several years.  Nusonics products  contribute less than 10
percent of our total sales.

     In fiscal 2003,  revenues  for the  Datatrace  brand of products  performed
exceptionally  well  increasing 28 percent.  The new  Micropack III  temperature
loggers were extremely  successful  during their first year in the  marketplace,
and propelled the temperature  logging products to an increase of 40 percent for
the fiscal year. Humidity logging instruments also produced a sharp increase for
the fiscal year improving more than 140 percent. Datatrace products were further
helped  during the year by a decline in the value of the US dollar  compared  to
the EURO which was helping  these  products  realize sales gains in the European
market.

     During fiscal 2003 the company's  medical products  declined 16 percent for
the fiscal year.  The major share of this  decrease was due to a decline in Echo
Dialyzer  Reprocessor sales, which had increased  dramatically in the prior year
due to a large order from a single  customer  that was not  repeated in the next
fiscal year.  Also, the expanded use of single use dialyzers in the U.S.  market
had  reduced  Reprocessor  demand.  Sales  of  the  hand-held  dialysate  meters
decreased by 11 percent  during the fiscal year,  after  several years of strong
growth.  Currently,  research and  development  efforts are beginning to further
enhance our line of hand-held dialysate meters.

Cost of Sales

     Cost of sales as a percent of net sales in fiscal 2004 increased two tenths
of one percent from fiscal 2003 to 37.6%, and in fiscal 2003 decreased 3.0% from
fiscal 2002 to 37.4% from 40.4% in fiscal 2002. Most of our products enjoy gross
margins in excess of 55%. Due to the fact that the dialysis  products have sales
concentrations  to several  companies  that  maintain  large chains of treatment
centers, the products that are sold to the renal market tend to be slightly more
price sensitive than the data logging products. Therefore, shifts in product mix
toward  higher sales of Datatrace  logging  products  will tend to produce lower
cost of good sold expense and higher gross  margins  while shifts  toward higher
sales of medical  products will normally  produce the opposite effect on cost of
goods sold expense and gross margins.


     Over fiscal year 2004, our Company saw a shift in its mix to higher medical
sales, which led to a slight increase in cost of goods sold expense as a percent
of sales compared to fiscal 2003. During fiscal 2003,  Datatrace logging devices
increased in sales as a percent of total sales.  Our logging  instruments have a
higher gross margin over the other  instruments  which we produce and sell. This
improvement  in sales mix was  partially  off-set by an  increase  in  Datatrace
export  sales,  which  are sold at a  discount  to the  company's  international
distributors and produce a lower gross margin.

Selling, General and Administrative

     General and administrative expenses tend to be fairly fixed and stable from
year-to-year.  To the  greatest  extent  possible,  we  work at  containing  and
minimizing these costs. Total administrative costs were $906,000 in fiscal 2004,
$904,000 in fiscal 2003 and $935,000 in fiscal 2002,  which  represents a $2,000
or less than one percent  increase from fiscal 2003 to fiscal 2004 and a $31,000
or three percent decrease from fiscal 2002 to fiscal 2003.  Higher  compensation
costs during  fiscal 2004 were  off-set by lower  consulting  fees,  while lower
costs for  business  development  activities  were  partially  off-set by higher
compensation costs during fiscal 2003.

     Our selling and marketing costs tend to be far more variable in relation to
sales,  although there are various exceptions.  Some of these exceptions include
the introduction of new products and the mix of international  sales to domestic
sales. For a product line experiencing introduction of a new product, costs will
tend to be higher as a percent  of sales due to higher  advertising  development
and sales  training  programs.  Our  Company's  international  sales are usually
discounted  and recorded at the net  discounted  price,  so that a change in mix
between  international  and domestic  sales may  influence  sales and  marketing
costs.  One other major  influence  on sales and  marketing  costs is the mix of
domestic  medical sales to all other domestic sales.  Domestic medical sales are
made by  direct  telemarketing  representatives,  which  gives  us a lower  cost
structure,  when  compared  to the  independent  representative  sales  channels
utilized by our other products.

     In dollars,  selling costs were  $1,211,000  in fiscal 2004,  $1,334,000 in
fiscal 2003 and  $1,225,000 in fiscal 2002. As a percent of sales,  selling cost
were 13.3% in fiscal 2004, 14.7% in fiscal 2003 and 13.5% in fiscal 2002. During
fiscal 2004,  most of the  decrease in selling  expense was due to a decrease in
costs associated with the Datatrace logging products.  Part was due to decreased
commissions  due to lower  sales  and the  remainder  was due to lower  bad debt
expense.  The  decrease  in bad  debt  expense  was  due to  higher  receivables
collection  in Europe,  which was brought  about by the increase in the value of
the Euro compared to the U.S.  Dollar.  The increase in selling  expense  during
fiscal  2003  was due  chiefly  to  increased  selling  and  marketing  cost for
Datatrace  products.  In  addition  to  increases  in  variable  costs,  such as
commissions, bonuses and travel, discretionary expenses, such as advertising and
demonstration  equipment  costs,  were increased  during the year to support the
introduction  of the Company's  new  Micropack  III products.  Selling costs for
medical products decreased due chiefly to lower  compensation  costs, which were
partially off-set by higher training costs.

Research and Development

     Company  sponsored  research  and  development  cost was $332,000 in fiscal
2004,  $260,000 in fiscal 2003 and  $290,000 in fiscal  2002.  We are  currently
trying to execute a strategy  of  increasing  the flow of  internally  developed
products. This strategy has led to the introduction of two new Datatrace logging
products in fiscal 2004 and a third  Datatrace  logging  product early in fiscal
2005.  Work has also begun on a new  generation of our  dialysate  meter line of
products. This has led to the increased research and development spending during
fiscal 2004. During fiscal 2003,  consulting expenses dropped  significantly and
were partially  off-set by substantially  higher material and supply expenses as
work  during  the  year  focused  more  on  hardware  development  and  software
development  projects  were  completed.  Besides  completing  the  Micropack III
product for temperature, work continued for humidity, pressure and 4-20 milliamp
versions of the Micropack III logger design.

Net Income

     Net income increased to a record  $2,130,000 or $.68 per share on a diluted
basis in fiscal  2004 from  $2,127,000  or $.64 per share on a diluted  basis in
fiscal 2003.  Actual net income grew less than one percent  during  fiscal 2004,
but diluted  per share  profits  grew six  percent  from year to year due to the
higher  net  income  and lower  average  shares  outstanding.  The lower  shares
outstanding were due to our continuing share buy back program.  This program has
continued  into the new fiscal  year,  and  depending on market  conditions,  is
expected  to continue  throughout  fiscal  2005.  The stock  repurchase  program
reduced outstanding common stock by 100,474 shares, and allowed diluted earnings
per share to grow at a faster rate than net income.

     Net income  increased to $2,127,000 or $.64 per share on a diluted basis in
fiscal 2003 from $2,031,000 or $.59 per share on a diluted basis in fiscal 2002.
The increase in net income  during  fiscal 2003 was partially due to the changes
in  product  mix  highlighted  in the  Cost of  Sales  section  of this  report.
Additionally, higher sales and lower administration and research and development
expenses  helped to increase  income.  During the fiscal  year,  we  repurchased
266,169 shares of our common stock.  While net income grew at a faster rate than
net sales for the fiscal year,  this growth was restrained by an increase in the
net income tax rate compared to last year.  This increase in the income tax rate
in 2003  compared  to 2002 was due  chiefly  to a change  in the tax code  which
reduced the benefit of export sales.

Liquidity and Capital Resources

     On March 31, 2004, we had cash and short term investments of $6,767,000. In
addition,  we had other current  assets  totaling  $3,970,000  and total current
assets of  $10,737,000.  Current  liabilities of our Company were $658,000 which
resulted in a current ratio of 16:1. For comparison  purposes at March 31, 2003,
we had cash and short term  investments of  $4,761,000,  other current assets of
$4,843,000, total current assets of $9,604,000,  current liabilities of $587,000
and a current ratio of 16:1.

     Our Company has made capital acquisitions of $34,000 during fiscal 2004 and
$65,000  during  fiscal 2003.  We have  instituted a program to repurchase up to
300,000 shares of our outstanding  common stock.  Under the plan, the shares may
be  purchased  from time to time in the open market at  prevailing  prices or in
negotiated  transactions  off the market.  Shares purchased will be canceled and
repurchases  will be made with existing cash reserves.  We do not maintain a set
policy or schedule  for our buyback  program.  Most of our stock  buybacks  have
occurred  during  periods  when the  price to  earnings  multiple  has been near
historical low points, or during times when selling activity in the stock is out
of balance with buying demand.

     On November 12, 2003 our Board of  Directors  declared for the first time a
regular  quarterly  dividend of $.05 per share of common stock.  In addition the
Board of  Directors  declared a special  one time  dividend of $.15 per share of
common stock.  Both dividends were paid on December 15, 2003, to shareholders of
record on December 1, 2003.  For fiscal year 2004,  dividends  totaled  $.25 per
common share of stock.

     Our  Company  invests  its  surplus  capital  in various  interest  bearing
instruments,  including money market funds,  short-term treasuries and municipal
bonds. All investments are fixed dollar investments with variable rates in order
to minimize the risk of principal loss. In some cases,  additional guarantees of
the investment principal are provided in the form of bank letters of credit.

     The Company does not currently  maintain a line of credit or any other form
of debt.  Nor does the  Company  guarantee  the debt of any  other  entity.  The
Company has maintained a long history of surplus cash flow from operations. This
surplus  cash  flow has been  used in the past to fund  acquisitions  and  stock
buybacks  and is  currently  being  partially  utilized  to  fund  our  on-going
dividend.  If  interesting  candidates  come to our  attention,  we may chose to
pursue  new  acquisitions,  but  currently  no  acquisitions  are  under  active
consideration.

Contractual Obligations

     At March 31,  2004 our only  contractual  obligations  were  open  purchase
orders for routine  purchases of supplies and inventory,  which would be payable
in less than one year.

Forward Looking Statements

     All statements  other than  statements of historical  fact included in this
annual  report  regarding  our  Company's  financial  position and operating and
strategic  initiatives and addressing industry  developments are forward-looking
statements.  Where,  in  any  forward-looking  statement,  the  Company,  or its
management,  expresses  an  expectation  or belief as to  future  results,  such
expectation  or  belief  is  expressed  in good  faith  and  believed  to have a
reasonable  basis,  but  there  can  be  no  assurance  that  the  statement  of
expectation or belief will result or be achieved or accomplished.  Factors which
could cause actual results to differ materially from those anticipated,  include
but are not limited to general  economic,  financial  and  business  conditions;
competition  in the data  logging  market;  competition  in the kidney  dialysis
market;  competition in the fluid measurement  market; the discontinuance of the
practice of dialyzer  reuse;  the business  abilities and judgment of personnel;
the impacts of unusual  items  resulting  from ongoing  evaluations  of business
strategies;  and changes in business strategy.  We do not intend to update these
forward looking statements. You are advised to review the "Additional Cautionary
Statements" section below for more information about risks that could affect the
financial results of Mesa Laboratories, Inc.

Critical Accounting Policies and Estimates

     The  preparation of our financial  statements in conformity with accounting
principles   generally  accepted  in  the  United  States  of  America  requires
management to make estimates and assumptions that affect the amounts reported in
our financial  statements and  accompanying  notes.  Actual results could differ
materially from those estimates.

     We believe that there are several accounting  policies that are critical to
understanding the Company's historical and future performance, as these policies
affect the reported amounts of revenue and the more significant  areas involving
management's  judgments and estimates.  These  significant  accounting  policies
relate to revenue  recognition,  research and  development  costs,  valuation of
inventory, and valuation of long-lived assets. These policies, and the Company's
procedures related to these policies, are described in detail below.

Revenue Recognition

     We  sell  our  products  directly  through  our  sales  force  and  through
distributors.  Revenue  from  direct  sales of our  product is  recognized  upon
shipment to the  customer.  Revenue from ongoing  product  service and repair is
fully  recognized upon completion and shipment of serviced  product.

Research & Development Costs

     Research  and  development  activities  consist  primarily  of new  product
development and continuing  engineering on existing  products.  Costs related to
research and development  efforts on existing or potential products are expensed
as incurred.

Valuation of Inventories

     Inventories are stated at the lower of cost or market,  using the first-in,
first-out   method  (FIFO)  to  determine  cost.  The  Company's  policy  is  to
periodically evaluate the market value of the inventory and the stage of product
life cycle,  and record a reserve for any  inventory  considered  slow moving or
obsolete.  As of March 31, 2004 and 2003 the  Company had  recorded a reserve of
$55,000 and $110,000, respectively, against slow moving inventory.

Valuation of Long-Lived Assets and Goodwill

     The Company assesses the realizable value of long-lived assets and goodwill
for  potential  impairment  at least  annually or when events and  circumstances
warrant such a review.  The carrying  value of a long-lived  asset is considered
impaired when the  anticipated  fair value is less than its carrying  value.  In
assessing the recoverability of our long-lived assets and goodwill, we must make
assumptions regarding estimated future cash flows and other factors to determine
the fair value of the respective  assets. In addition,  we must make assumptions
regarding the useful lives of these  assets.  As of March 31, 2004, we evaluated
our long-lived  assets for potential  impairment.  Based on our  evaluation,  no
impairment charge was recognized.

     The above listing is not intended to be a comprehensive  list of all of our
accounting  policies.  In many cases,  the accounting  treatment of a particular
transaction  is  specifically  dictated  by  accounting  principles,   generally
accepted in the United States of America, with no need for management's judgment
in their  application.  There are also areas in which  management's  judgment in
selecting  any  viable  alternative  would not  produce a  materially  different
result.  See our audited  financial  statements and notes thereto which begin at
"Item 7.  Financial  Statements"  of this  Annual  Report on Form  10-KSB  which
contain  accounting  policies  and  other  disclosures  required  by  accounting
principles, generally accepted in the United States of America.

Additional Cautionary Statements

We Face Intense Competition

     The markets for some of our current and  potential  products are  intensely
competitive.  We face  competition from companies that possess both larger sales
forces and  possess  more  capital  resources.  In  addition,  there are growing
numbers of competitors for certain of our products.

Our Growth  Depends on  Introducing  New Products and the Efforts of Third Party
Distributors

     Our growth  depends on the  acceptance of our products in the  marketplace,
the  penetration  achieved  by the  companies  which we sell to, and rely on, to
distribute  and  represent  our  products,  and our ability to introduce new and
innovative  products that meet the needs of the various markets we serve.  There
can be no  assurance  that we will be able  to  continue  to  introduce  new and
innovative products or that the products we introduce, or have introduced,  will
be widely accepted by the  marketplace,  or that the companies which we contract
with to distribute  and  represent  our products  will continue to  successfully
penetrate our various markets. Our failure to continue to introduce new products
or gain wide  spread  acceptance  of our  products  would  adversely  affect our
operations.

We Depend on Attracting New Distributors and Representatives for Our Products

     In order to successfully commercialize our products in new markets, we will
need  to  enter  into   distribution   arrangements   with  companies  that  can
successfully distribute and represent our products into various markets.

Our Products are Extensively Regulated Which Could Delay Product Introduction or
Halt Sales

     The process of obtaining and maintaining  required regulatory  approvals is
lengthy,  expensive  and  uncertain.   Although  we  have  not  experienced  any
substantial  regulatory  delays to date,  there is no assurance that delays will
not occur in the future,  which could have a significant  adverse  effect on our
ability  to  introduce  new  products  on a timely  basis.  Regulatory  agencies
periodically  inspect our manufacturing  facilities to ascertain compliance with
"good  manufacturing  practices" and can subject approved products to additional
testing and surveillance programs.  Failure to comply with applicable regulatory
requirements can, among other things, result in fines,  suspension of regulatory
approvals, product recalls, operating restrictions and criminal penalties. While
we  believe  that we are  currently  in  compliance,  if we fail to comply  with
regulatory  requirements,  it could  have an  adverse  effect on our  results of
operations and financial condition.

We May be Unable to Effectively Protect Our Intellectual Property

     Our  ability  to compete  effectively  depends  in part on  developing  and
maintaining the proprietary  aspects of our technology and processes.  We cannot
assure you that the patents we have obtained, or any patents we may obtain, will
provide any competitive  advantages for our products.  We also cannot assure you
that  those  patents  will  not  be  successfully  challenged,   invalidated  or
circumvented in the future. In addition,  we cannot assure you that competitors,
many of which have substantial  resources and have made substantial  investments
in competing technologies, have not already applied for or obtained, or will not
seek to apply for or obtain,  patents that will prevent, limit or interfere with
our ability to make, use and sell our products either in the United States or in
international  markets.  Patent  applications  are  maintained  in secrecy for a
period  after  filing.  We may not be aware  of all of the  patents  and  patent
applications potentially adverse to our interests.

We May Have Product Liability Claims

     Our  products  involve a risk of  product  liability  claims.  Although  we
maintain  product  liability  insurance at coverage  levels which we believe are
adequate,  there is no assurance that, if we were to incur substantial liability
for product liability claims,  insurance would provide adequate coverage against
such liability.

Changing Accounting Regulation May Affect Operating Results

     Our Operating results may be adversely  affected by new laws and accounting
regulations   that  have  either  been  recently  enacted  or  which  are  under
consideration and may include the following:

*    various regulations of the Sarbanes-Oxley Act, and
*    the mandatory expensing of employee stock options as proposed by the FASB.

Our Operating Results May Fluctuate

     Our results of  operations  may  fluctuate  significantly  from  quarter to
quarter based on numerous factors including the following:

*    the introduction of new products;
*    the level of market acceptance of our products;
*    achievement of research and development milestones;
*    timing of the  receipt  of  orders  from,  and  product  shipment  to major
     customers;
*    timing of expenditures;
*    delays in educating  and training our  distributors'  and  representatives'
     sales forces;
*    manufacturing or supply delays;
*    product returns; and
*    receipt of necessary regulation approval.

Changing Industry Trends May Affect Operating Results

     Various  changes within the industries we serve may limit future demand for
our products and may include the following:

*    increasing usage of single use dialyzers;
*    changes in dialysis reimbursements; and
*    increased availability of donated organs.

                          INDEPENDENT AUDITORS' REPORT



Board of Directors and Stockholders
Mesa Laboratories, Inc.
Lakewood, Colorado

We have audited the accompanying balance sheets of Mesa Laboratories, Inc. as of
March 31, 2004 and 2003,  and the related  statements  of income,  stockholders'
equity, and cash flows for the years then ended. These financial  statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the  United  States of  America.  Those  standards  require  that we plan and
perform the audit to obtain  reasonable  assurance  about  whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects,  the financial position of Mesa Laboratories,  Inc. as of
March 31, 2004 and 2003,  and the results of its  operations  and its cash flows
for the years then ended,  in conformity with  accounting  principles  generally
accepted in the United States of America.

                          NOTES TO FINANCIAL STATEMENTS

1.   Summary of Significant Accounting Policies:

General - Mesa  Laboratories,  Inc. was incorporated under the laws of the State
of Colorado on March 26, 1982, for the purpose of designing,  manufacturing  and
marketing electronic instruments and supplies.

Concentration of Credit Risk - Financial  instruments which potentially  subject
the Company to  concentrations  of credit risk  consist of money  market  funds,
short-term  investments and accounts  receivable.  The Company invests primarily
all of its excess cash in money market funds administered by reputable financial
institutions,  debt  instruments  of  the  U.S.  government  and  its  agencies,
adjustable  rate, fixed dollar municipal debt and grants credit to its customers
who are located throughout the United States and several foreign  countries.  To
reduce  credit risk,  the Company  periodically  evaluates the money market fund
administrators  and performs  credit  analysis of customers  and monitors  their
financial condition.  Additionally,  the Company maintains cash balances in bank
deposit  accounts  which, at times,  may exceed  federally  insured limits.  The
Company has not experienced any losses in such accounts.

During  the  fiscal  year  ended  March  31,  2004,  one  customer   represented
approximately  12%  of  the  Company's  revenues  and  approximately  11% of the
Company's accounts  receivable  balance.  During the fiscal year ended March 31,
2003 one customer  represented  approximately 11% of the Company's  revenues and
approximately 6% of the Company's account receivable balances.

Cash Equivalents - Cash equivalents  include all highly liquid  investments with
an original maturity of three months or less.

Short-term  investments - Short-term  investments consists of U.S Treasury bills
and  municipal  bonds and are  classified as  "available  for sale."  Short-term
investments are carried in the financial  statements at cost, which approximates
fair value.

Accounts  Receivable  - At the time the  accounts  are  originated,  the Company
considers a reserve for doubtful accounts based on the  creditworthiness  of the
customer.  The provision for uncollectible  amounts is continually  reviewed and
adjusted to  maintain  the  allowance  at a level  considered  adequate to cover
future  losses.  The allowance is  management's  best estimate of  uncollectible
amounts and is determined based on historical performance that is tracked by the
Company on an  ongoing  basis.  The  losses  ultimately  incurred  could  differ
materially  in the near term  from the  amounts  estimated  in  determining  the
allowance.

Inventories - Inventories  are stated at the lower of cost or market,  using the
first-in,  first-out method (FIFO) to determine cost. The Company's policy is to
periodically evaluate the market value of the inventory and the stage of product
life cycle,  and record a reserve for any  inventory  considered  slow moving or
obsolete.  As of March 31, 2004 and 2003 the  Company had  recorded a reserve of
$55,000 and $110,000, respectively, against slow moving inventory.

Property,  Plant and  Equipment -  Property,  plant and  equipment  is stated at
acquisition   cost.   Depreciation   and  amortization  is  provided  using  the
straight-line  method over the  estimated  useful lives of three to  thirty-nine
years.

Goodwill - Goodwill, which resulted from the acquisitions of Nusonics, Datatrace
and Automata,  is no longer subject to amortization,  and is tested annually for
impairment  in  accordance  with  Statement  of Financial  Accounting  Standards
("SFAS") No. 142 "Goodwill and Intangible Assets."

Valuation of Long-Lived  Assets - The Company  assesses the realizable  value of
long-lived  assets and goodwill for potential  impairment  at least  annually or
when events and  circumstances  warrant such a review.  The carrying  value of a
long-lived asset is considered  impaired when the anticipated fair value is less
than its carrying  value.  In assessing  the  recoverability  of our  long-lived
assets and goodwill,  we must make assumptions  regarding  estimated future cash
flows and other factors to determine the fair value of the respective assets. In
addition,  we must make assumptions  regarding the useful lives of these assets.
As of  March  31,  2004,  we  evaluated  our  long-lived  assets  for  potential
impairment. Based on our evaluation, no impairment charge was recognized.

Revenue  Recognition - The Company recognizes  revenues at the time products are
shipped.  Revenue from ongoing  product  service and repair is fully  recognized
upon completion and shipment of serviced product.

Research & Development Costs - Costs related to research and development efforts
on  existing or  potential  products  are  expensed as  incurred.  Research  and
development  costs for the  fiscal  years  ended  March  31,  2004 and 2003 were
$331,740 and $259,966, respectively.

Accrued  Warranty Expense - The Company provides limited product warranty on its
products and,  accordingly,  accrues an estimate of the related warranty expense
at the time of sale.

Advertising  Costs -  Advertising  costs are expensed as  incurred.  Advertising
costs for the years ended March 31, 2004 and 2003 were  $138,135  and  $140,728,
respectively.

Income Taxes - The Company accounts for income taxes under the liability method,
which  requires  an entity to  recognize  deferred  tax assets and  liabilities.
Temporary  differences  are  differences  between  the tax basis of  assets  and
liabilities  and their reported  amounts in the financial  statements  that will
result in taxable or deductible amounts in future years.

Earnings Per Share - Basic  earnings per share is  calculated  using the average
number of common shares  outstanding.  Diluted earnings per share is computed on
the basis of the average number of common shares  outstanding plus the effect of
outstanding stock options using the treasury stock method,  which totaled 83,238
and 72,587 additional shares in 2004 and 2003, respectively.

Stock  based  compensation  - At March 31,  2004,  the  Company  has stock based
compensation  plans,  which are described  more fully in Note 7. The Company has
adopted the  disclosure-only  provisions  of Statement  of Financial  Accounting
Standards No. 123, "Accounting for Stock-Based

Compensation."  Accordingly,  no  compensation  cost has been recognized for the
stock option plans. Had  compensation  cost for the Company's stock option plans
been determined based on the fair value at the grant date for awards in 2004 and
2003  consistent with the provisions of SFAS No. 123, the Company's net earnings
and earnings per share would have been reduced to the pro forma amount indicated
below:


                                                         March 31,

                                                   ----------   ----------

Net income - as reported .......................   $2,129,681   $2,126,879
Less: Total stock based compensation expense
    determined under fair value based method for
     all awards net of related tax effects .....       89,768      106,444
                                                   ----------   ----------

Net income - pro forma .........................   $2,039,913   $2,020,435
                                                   ==========   ==========

Income per diluted share - as reported .........   $      .68   $      .64
Income per diluted share - pro forma ...........   $      .65   $      .61

The fair value of each option  grant is estimated on the date of grant using the
Black-Scholes   option-pricing   model  with  the   following   weighted-average
assumptions  used for  grants:  dividend  yield of 2.1%  (2004)  and 0%  (2003);
expected volatility of approximately 29% (2004) and 20% (2003); discount rate of
3.0% (2004) and 3.0% (2003); and expected lives of 5 years.

Use of Estimates - The  preparation of financial  statements in conformity  with
accounting  principles  generally  accepted  in the  United  States  of  America
requires  management to make estimates and assumptions  that affect the reported
amounts  of assets and  liabilities  and  disclosure  of  contingent  assets and
liabilities at the date of the financial  statements and the reported amounts of
revenues and expenses during the reporting  period.  Actual results could differ
from those estimates.

Fair  Value  of  Financial  Instruments  -  The  carrying  amount  of  financial
instruments including cash and cash equivalents, accounts receivable, short-term
investments, accounts payable and accrued expenses approximated fair value as of
March 31, 2004 because of the relatively short maturity of these instruments.

Recently Issued Accounting  Pronouncements - In April 2003, FASB issued SFAS No.
149,  "Accounting for Derivative  Instruments and Hedging  Activities," which is
effective  for  contracts  entered into or modified  after June 30, 2003 and for
hedging relationships  designated after June 30, 2003. This statement amends and
clarifies  financial   accounting  and  reporting  for  derivative   instruments
including  certain  instruments  embedded  in other  contracts  and for  hedging
activities  under SFAS No.  133,  "Accounting  for  Derivative  Instruments  and
Hedging  Activities."  The  adoption of this  standard is not expected to have a
material impact on the Company's financial statements.


In May 2003,  FASB  issued  SFAS No.  150,  "Accounting  for  Certain  Financial
Instruments  with  Characteristics  of Both  Liabilities  and Equity,"  which is
effective for financial instruments entered into or modified after May 31, 2003,
and  otherwise  is  effective  at the  beginning  of the  first  interim  period
beginning  after June 15, 2003.  SFAS No. 150  establishes  standards for how an
issuer   classifies   and   measures   certain   financial    instruments   with
characteristics of both liabilities and equity. The adoption of this standard is
not expected to have a material impact on the Company's financial statements.

5.   Stock Repurchase:

In June,  2003, the Company's Board of Directors  approved program to repurchase
up to 300,000 shares of its outstanding common stock. Under the program,  shares
may be purchased from time to time in the open market at prevailing prices or in
negotiated  transactions off the market.  Shares purchased will be cancelled and
repurchase of shares will be funded through existing cash reserves.

6.   Employee Benefit Plan:

The Company adopted a 401(k) plan effective  January 1, 2000.  Participation  is
voluntary  and  employees  are eligible to  participate  at age 21 and after six
months of employment with the Company. The Company matches 50% of the employee's
contribution  up to 6% of the  employees  salary.  A  participant  vests  in the
Company's  contributions  at a rate of 25% per year, fully vesting at the end of
the participant's fourth year of service. The Company contributed $51,064 to the
plan for fiscal 2004 and $52,617 for fiscal 2003.

7.   Stockholders' Equity:

The State of Colorado has  eliminated  the ability of Colorado  corporations  to
retain  treasury  stock.  As a result,  the Company  reduced common stock to its
average share value and further reduced  retained  earnings for the remainder of
the cost of treasury stock acquired in each fiscal year.

During 2004 the Company discovered an inconsistency between the number of shares
of common stock  reported in its financial  statements  and the Company's  stock
transfer  agent records.  The Company has restated its common stock  outstanding
numbers in its financial  statements to correct this inconsistency.  This change
had no effect on any previously reported earnings per share information.

The Company  has adopted  incentive  stock  option  plans for the benefit of the
Company's key employees, excluding its outside directors. Under the terms of the
plans,  options  are granted at an amount not less than 100% of the bid price of
the underlying  shares at the date of grant.  The options are  exercisable for a
term of five years and, during such term, may be exercised as follows: 25% after
each year,  and 100%  anytime  after the fourth  year until the end of the fifth
year.

On October 3, 1996, the Company adopted a nonqualified  performance stock option
plan for the benefit of the Company's outside Directors.  The plan provides that
the outside  Directors  will receive grants to be determined and approved by the
Company's  inside  Directors  and not to  exceed  20,000  options  per  year per
director. Under the terms of the plan, the options are exercisable for a term of
ten years and, during such term are exercisable as follows: 25% after each year,
and 100%  anytime  after the fourth  year until the end of the tenth  year.  The
purchase price of the common stock will be equal to 100% of the closing price of
the common stock on the over-the-counter market on the date of grant.

On October 21, 1999,  the Company  adopted a new stock  compensation  plan.  The
purpose of the plan is to encourage ownership of the Common Stock of the Company
by certain officers, directors, employees and certain advisors of the Company in
order to provide incentive to promote the success and business of the Company. A
total of 300,000  shares of Common Stock have been  reserved for issuance  under
the plan and are subject to terms as set by the  Compensation  Committee  of the
Board of Directors at the time of grant.

All option plans have been approved by the stockholders of the Company.

The following is a summary of options granted under the plans:

ITEM 8.  CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE.

         None.


ITEM 8A.  CONTROLS AND PROCEDURES.

     As of the end of the period covered by this Annual Report on Form10-KSB, we
carried out an evaluation,  under the supervision and with the  participation of
our  management,  including  the Chief  Executive  Officer  and Chief  Financial
Officer,  of the  effectiveness  of the design and  operation of our  disclosure
controls and procedures  pursuant to Exchange Act Rule 13a-14 and 15d-14.  Based
upon  that  evaluation,  the Chief  Executive  Officer  and the Chief  Financial
Officer  concluded that our disclosure  controls and procedures are effective in
timely alerting them to material information relating to the Company required to
be included in our periodic SEC filings.

     Subsequent to the date of that  evaluation,  there have been no significant
changes in our internal  controls or in other  factors that could  significantly
affect internal  controls,  nor were any corrective actions required with regard
to significant deficiencies and material weaknesses.

     The  requirements  to provide (i) a report of  management  on our  internal
controls over  financial  reporting and (ii) our  registered  public  accounting
firm's  attestation  report on management's  assessment of our internal  control
over financial reporting are not yet applicable to us.

Compensation of Directors

     On October 3, 1996,  the  Company  adopted a new  nonqualified  performance
stock option plan for the benefit of the Company's outside  Directors.  The plan
provides that the outside  Directors  will receive  grants to be determined  and
approved by the Company's  inside directors and not to exceed 20,000 options per
year per director.  Under the terms of the plan, the options are exercisable for
a term of ten years, and during such term are exercisable as follows:  25% after
each year,  and 100%  anytime  after the fourth  year until the end of the tenth
year.  The  purchase  price  of the  common  stock  will be equal to 100% of the
closing bid price of the common stock on the over-the-counter market on the date
of grant.

     On June 19, 2003,  Mr. Brooks and Mr.  Campbell,  outside  directors,  were
granted options to purchase 4,000 shares of common stock at $7.00 per share. Mr.
Duke, a director who retired from his position as an executive  officer in March
2002,  was  granted  4,000  shares  of  common  stock at $7.00  per  share.  Mr.
Schmieder,  the Company's  inside director was granted options to purchase 4,000
shares of common stock at a price of $7.00 per share.

     Currently,  all outside  directors  receive cash compensation of $1,000 for
each Board of Directors or committee  meeting  attended in person,  and $300 for
each Board of Directors or committee meeting attended by teleconference.

Incentive Stock Option Plans

     The Company has adopted three incentive stock option plans, approved by the
shareholders of the Company in September  1984,  October 1989 and November 1993,
respectively,  for  the  benefit  of the  Company's  employees.  The  plans  are
administered  by the  non-participating  members of the Board of Directors,  who
select the optionees and determine the terms and  conditions of the stock option
grant.  The exercise  price for options  granted  under the plans cannot be less
than the  fair  market  value of the  stock at the date of grant or 110% of such
fair market value with respect to options granted to any optionee who holds more
than 10% of the Company's  common stock.  Options are not exercisable  until one
year after the date of grant and expire five years after the date of grant.  All
outstanding  options  are  subject to vesting  provisions  whereby  they  become
exercisable over a four-year period.  The plans authorize options to purchase up
to 200,000, 300,000 and 300,000 shares of common stock, respectively.

     On October 21, 1999, the Company adopted a new stock compensation plan. The
purpose of the plan is to encourage ownership of the Common Stock of the Company
by certain officers, directors, employees and certain advisors of the Company in
order to provide incentive to promote the success and business of the Company. A
total of 300,000  shares of Common Stock have been  reserved for issuance  under
the plan and are subject to terms as set by the  Compensation  Committee  of the
Board of Directors at the time of grant.

     As of March 31,  2004,  options to purchase a total of 265,070  shares were
outstanding,  at exercise prices ranging from $3.75 to $9.20 per share. Further,
as of March 31,  2004,  options to  purchase  an  aggregate  of  139,100  shares
remained  available for grant under the Company's  stock option plans.  The plan
adopted in September  1984 was terminated  effective June 1, 1993.  Options were
granted  during the fiscal year ended March 31, 2004,  pursuant to the Company's
incentive  stock option  plans,  to each of the  Company's  executive  officers.
Options to purchase  4,000 shares at $7.00 per share were granted to Mr.  Steven
W. Peterson,  Vice  President-Finance.  Mr. Luke R.  Schmieder,  President,  was
granted options to purchase 4,000 shares at $7.00 per share.

Retirement Plan

     The Company has adopted a 401(k) plan for the benefit of its  officers  and
employees. Subject to certain restrictions, a participant may defer up to 15% of
their gross  compensation  into the plan. The Company currently matches up to 6%
of the participant's contribution at a rate of 50% of the contribution. The plan
also allows for additional contributions by the Company at its discretion.
