                             MESA LABORATORIES, INC.
                          NOTES TO FINANCIAL STATEMENTS
                           DECEMBER 31, 2003 AND 2002

NOTE A. SUMMARY OF ACCOUNTING POLICIES

     The  summary  of  the   Issuer's   significant   accounting   policies  are
incorporated by reference to the Company's annual report on Form 10KSB, at March
31, 2003.

     The  accompanying  unaudited  condensed  financial  statements  reflect all
adjustments  which,  in the  opinion of  management,  are  necessary  for a fair
presentation  of the results of operations,  financial  position and cash flows.
The results of the interim period are not necessarily  indicative of the results
for the full year.

NOTE B. STOCK BASED COMPENSATION

     The Company has stock based  compensation  plans,  which are described more
fully in Note 7 of the Company's annual report on Form 10KSB, at March 31, 2003.
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 fiscal  2004
and 2003  consistent  with the  provisions  of SFAS No. 123, the  Company's  net
earnings and earnings  per share for the fiscal third  quarter and  year-to-date
would have been reduced to the pro forma amount indicated below:

assumptions  used for  grants:  dividend  yield of 2.0%  (2004)  and 0%  (2003);
expected volatility of approximately 14% (2004) and 20% (2003); discount rate of
3.0% (2004) and (2003); and expected lives of 5 years.


ITEM 2. MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
           OF OPERATIONS

LIQUIDITY AND CAPITAL RESOURCES

     On December 31, 2003,  the Company had cash and  short-term  investments of
$6,289,111.   In  addition,  the  Company  had  other  current  assets  totaling
$3,951,111 and total current assets of $10,240,222.  Current liabilities of Mesa
Laboratories, Inc. were $585,613, which resulted in a current ratio of 17.5:1.

     The Company has made net capital asset  purchases of $30,975 for the fiscal
year-to-date.

     The Company has  instituted a program to repurchase up to 300,000 shares of
its 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.  During the first nine months of the
fiscal year, the Company repurchased 87,000 shares of our common stock.

     On November  12, 2003 the  company's  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.

RESULTS OF OPERATIONS

REVENUE

     Net sales for the nine months ended December 31, 2003 increased  $47,578 or
1% to  $6,728,767  from the  $6,681,189  net sales level  achieved  for the same
nine-month  period last year. Net sales for the quarter increased $2,875 or less
than 1% to $2,199,740  from the  $2,196,865 net sales level achieved in the same
quarter last year.  Over the first nine months of the fiscal year,  revenues are
up a small amount  compared to prior year.  Datatrace  sales for the  nine-month
period produced a seven percent decline while medical  instruments  increased by
approximately  eight  percent.  Nusonics  products  have  increased  over twenty
percent for the same  period,  but this gain is on a much smaller base of sales.
Net sales for the quarter  were up a small  amount from the prior year  quarter.
For the  quarter,  medical  products  decreased  approximately  two  percent and
Nusonics  products were almost  unchanged.  Datatrace  products  decreased seven
percent from the prior year  quarter,  which was helped by initial  shipments of
the Micropack III product.

COST OF GOODS SOLD

     Cost of goods sold for the first nine  months as a percent of net sales was
38%,  which is an  increase  of 1% from the 37%  level  for the same  nine-month
period last year. Cost of goods sold for the current quarter as a percent of net
sales was 38%,  representing a 2% increase compared to the 36% level in the same
quarter last year. While the mix of products during the first nine months of the
fiscal year made a shift to Medical products compared to prior year leading to a
one percent change in the cost of goods sold as a percent of sales,  the quarter
saw an increase of two percent in cost of goods sold due to the lower  Datatrace
product sales described above.

SELLING, GENERAL AND ADMINISTRATIVE

     Selling,  general  and  administrative  expenses  for the first nine months
decreased 3% or $49,249 to  $1,587,766  from  $1,637,015 in the same period last
year. For the current  quarter,  selling,  general and  administrative  expenses
totaled  $523,762,  which was down 7% or $38,181 from  $561,943  expended in the
same quarter last year.  Marketing expenses decreased 14 percent and two percent
for the quarter and nine month  periods,  respectively  with  Medical  marketing
expenses  declining six percent for the quarter and nine month periods  compared
to the prior year.  Datatrace  marketing  expenses  decreased 16 percent for the
quarter and increased  two percent for the  nine-month  period.  The decrease in
marketing  expenses  for  Datatrace  products for the quarter was due chiefly to
lower bad debt expense.  Individual marketing costs for medical products trended
down for the quarter and nine month periods and were relatively unchanged within
the major expense categories. Administration costs remained at consistent levels
increasing  four percent in the current  quarter and declining five percent over
the first nine months of the fiscal year compared to the previous year.

RESEARCH AND DEVELOPMENT

     Research and  development  for the first nine months  increased to $236,391
from $199,636,  which represents an 18% increase from the same period last year.
Research  and  development  for the quarter was  $85,927,  which  represents  an
increase of $15,220 or 22% from the $70,707  level  expensed in the same quarter
last year.  Research and  development  costs  increased for the quarter and nine
month periods due to higher  compensation  and consulting  costs.  This trend is
expected  to  continue  throughout  the fiscal  year.  Development  of three new
versions of the Micropack III Logger that will measure other parameters  besides
temperature is proceeding well.  Development  projects for the company's line of
Dialysate  Meters for kidney  dialysis have begun,  and we estimate that we will
begin to introduce our next  generation  medical  instruments in the next fiscal
year.

NET INCOME

     Net income for the nine months  ended  December  31, 2003  decreased  4% to
$1,551,643  from  $1,619,402,  but earnings  per share  increased 2% to $.50 per
diluted  share  compared to $.49 per diluted  share one year ago. Net income for
the quarter was  $500,162  or $.16 per diluted  share  compared to net income of
$538,595 or $.17 per diluted share last year. For the quarter and  year-to-date,
net income  compared  to last year  declined  slightly  due to  unchanged  sales
performance,  a shift in sales mix from  Datatrace  to Medical  products  and an
increase in the income tax rate  compared to the prior year.  On an earnings per
share basis,  year-to-date net income increased by $.01 per diluted share due to
the lower outstanding shares generated by the company's share buyback program.

ITEM 3. Controls and Procedures

     a. Evaluation of Disclosure  Controls and  Procedures.  The Company's Chief
Executive Officer and Chief Financial Officer,  have evaluated the effectiveness
of the Company's  disclosure controls and procedures (as such term is defined in
Rules  13a-14(c) and  15d-14(c)  under the  Securities  Exchange Act of 1934, as
amended (the Exchange Act)) as of a date within 90 days prior to the filing date
of this quarterly report (the Evaluation Date).  Based on such evaluation,  such
officers  have  concluded  that,  as  of  the  Evaluation  Date,  the  Company's
disclosure  controls and  procedures are effective in alerting them, on a timely
basis,  to  material   information   relating  to  the   Company(including   its
consolidated  subsidiaries)  required to be included in the  Company's  periodic
filings under the Exchange Act.

     b. Changes in Internal Controls.  Since the Evaluation Date, there have not
been any  significant  changes in the  Company's  internal  controls or in other
factors that could significantly affect such controls.
