280-10-50-1 as this relates to segment reporting within our operations.&#160; Mesa Labs currently manufactures and sells
electronic measurement instruments and disposables, which are manufactured in
two separate plants.&#160; Currently Mesa Labs
operates as a single entity manufacturing and selling instruments and disposables
utilized for quality control in various industries including medical,
pharmaceuticals and food processing.&#160; We
stated on page&nbsp;41 that the company &#147; aggregates its segments as one
reportable segment based on the similar characteristics of their operations.&#148;&#160; This statement should have been worded&#160;&#160; &#147; aggregates its <i>product
lines</i> as one reportable segment based on the similar characteristics
of their operations.&#148;</font></p>

<p style="margin:0in 0in .0001pt .75in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">A.&nbsp;&nbsp;You
have asked us to confirm that our five product lines as disclosed in this note
as of March&nbsp;31, 2010, do not meet the definition of operating segments as
defined in FASB ASC 280-10-50-1.&#160; As we
have stated in our previous responses, our products crossover industries and
markets and internal personnel, we do not financially track these product lines
as separate segments internally and we confirm that it is our belief that these
product lines do not represent segments per FASB ASC 280-10-50-1.</font></p>

<p style="margin:0in 0in .0001pt .75in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">B.&nbsp;&nbsp;You
have asked which criteria outlined in the guidance on ASC 280-10-50-1 has not
been met.&#160; We believe that both criteria
b. (Its operating results are regularly reviewed by the public entity&#146;s chief
operating decision maker to make decisions about resources to be allocated to
the segment and assess its performance.) and criteria c. (Its discrete
financial information is available) have not been met.&#160; As stated in our other responses, our
financial information is not fully tracked by management to give us
profitability beyond the gross profit level.&#160;
We do not track operating income for any of our product lines.&#160; Our decisions on the allocation of resources
are made to very specific levels. We make our decisions on the individual
products.&#160; The amount of resources
allocated is specifically linked to the potential return of the actual project,
whether it is a piece of capital equipment, a contract or an R&amp;D
project.&#160; It is also important to note
that none of our product lines has an individual manager overseeing all
operational, sales and marketing and R&amp;D decisions other than our CEO.</font></p>

<p style="margin:0in 0in .0001pt .75in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The
table above shows our operating structure from left to right.&#160; The CEO/President is over all operations of
Mesa Labs.&#160; Under the CEO/President is
the CFO, V.P. Sales and Marketing, Q.A. Director, R&amp;D Director
Manufacturing Director &#151; Lakewood, CO and General Manager &#151; Raven.&#160; The CFO manages all administrative operations
and accounting personnel at both the Lakewood and Raven (Omaha, NE) location.
The V.P. Sales and Marketing manages marketing, and sales at all
locations.&#160; The staff is also spread over
these two locations.&#160; Marketing for all
operations is managed by a manager located at the Raven operation.&#160; All sales personnel report to the V.P. Sales
and Marketing in Lakewood.&#160; Our Q.A.
Director is based at Raven and manages the Raven operations directly and the
Lakewood operations through a manager based in Lakewood reporting to the
director.&#160; The Operations Director &#151;
Lakewood manages all manufacturing, purchasing, warehouse and facility
operations at the Lakewood plant.&#160; The
General Manager - Raven manages all manufacturing, purchasing, warehouse and
facility operations at the Raven facility.&#160;
At this time, all decisions on major contracts (OEM, Distribution,&nbsp;etc.),
capital purchases, employee benefits (Health Insurance, Vacation Policies,&nbsp;etc.),
marketing strategy,&nbsp;etc. are made by the CEO/President.&#160; There is no one individual who makes both
sales and marketing and manufacturing decisions for any of our product lines.&#160; There is no business manager other than the
CEO that makes a decision for all aspects of our product lines.</font></p>

<p style="margin:0in 0in .0001pt .75in;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">D.&nbsp;&nbsp;Financial
information reviewed by Mesa Labs management includes a total balance sheet in
standard format.&#160; All accounts are in
this single balance sheet.&#160; We book all
accounts receivables, inventory, fixed assets, accounts payable,&nbsp;etc.
transactions to single general ledger accounts.&#160;
Any reporting below this level is typically accomplished by responsible
managers by running sorted reports over ranges (customer no., warehouse,&nbsp;etc.)
as needed.&#160; We use two different income
statements.&#160; The first is a total income
statement with all accounts.&#160; This income
statement does all normal totaling including sales, cost of goods sold, gross
profits,&nbsp;etc.&#160; The second income
statement is sorted by department.&#160; For
each product line, there is a sales, manufacturing overhead, service overhead,
and marketing and sales department.&#160; We
also maintain departments that are not allocated or assigned to specific product
lines which include materials control, facilities, quality assurance, customer
service, R&amp;D and administration.&#160; As
stated previously,&#160; these department
reports allow us to track sales, cost of goods sold and sales and marketing to
product line.&#160; We do not produce reports
tracking beyond this level.&#160; Since we are
operating as a single segment, we make no attempt to produce income reporting
beyond the gross profit level.&#160; Resources
are allocated based on our judgment of best return for a project or individual
product.</font></p>

question regarding decisions to possibly sell a product line is based on the

would not significantly </font></p>

the fixed costs of the company.&#160;
Departments such as materials control, facilities, quality assurance,
R&amp;D and administration would not be significantly reduced due to sales of a
product line.&#160; Additionally, since our
customers overlap between product lines, we consider the risk to our own
reputation if an acquirer of one of our product lines should fail in service or
quality to be too high of a risk to our own reputation.&#160; We would also have issues with separating
equipment used in our manufacturing processes in some cases.</font></p>
