Mission: Enable Army readiness through accuracy.

Vision: Be the world-renowned metrology enterprise, sustaining the strength of the nation.


The U.S. Army Test, Measurement, and Diagnostic Equipment Activity (USATA) has the primary organizational responsibility of performing the test, measurement, and diagnostic equipment (TMDE) calibration and repair mission for the Army, other DOD claimants, and thousands of reimbursable customers. USATA provides measurement traceability to the International System of Units. USATA’s TMDE calibration support mission is the keystone of the Army diagnostic and maintenance program. We assure TMDE reliability by ensuring accurate interval setting.


Need for Calibration

It’s not uncommon for consumers to drive across town to a fuel station that offers gas for a penny less per gallon than the convenient mart closer to home. It’s a trip we’ve all taken, trying to get the best deal possible. But were you getting your money’s worth?
Many consumer products are priced against a unit of measure. Gas is sold by the gallon, meat by the pound, and flooring by the square foot. How can you be sure that 10 gallons are going into your tank unless the pumps are checked periodically?


Guiding Principles

Quality. We believe that the quality of our measurements must not be compromised. We are continually improving our measurement systems, measurement procedures, measurement assurance, and technical skills to ensure delivery of quality products and services to our customers. Although the needs of the Warfighter come first, all customers will receive the same quality service. Quality of our measurements is critical to readiness and safety.

Customers. We believe that customer satisfaction is essential to successfully fulfilling our role within the Army and DOD.



Metrology and Calibration

Metrology is defined as the science of measurement and is derived from the Greek word “metron” meaning “to measure”. Measurement is one of the oldest of the sciences. The rise of man from his primitive state to modern civilization seems to be directly related to his capability to measure. One example of measurement by the ancient Babylonians (before 3000 BC), and still used today, is the system of measuring time.
