In-Lab & Onsite Calibration Services in Denver, CO
With over 35 years of experience, our technicians have provided precise calibration, instrument repair, and metrology database management to a diverse range of industries across the Denver area.
Located in Gaithersburg, MD, our calibration laboratory—accredited to ISO/IEC 17025:2017, ANSI Z540-1, and Z540.3 standards—adheres to strict quality protocols. We perform all calibrations and repairs in line with manufacturer specifications to ensure your measurement tools remain reliable, repeatable, and audit-ready. Each calibration is accompanied by a certificate that confirms compliance with the rigorous standards set by the National Institute of Standards and Technology (NIST).
Serving Denver, CO
Denver anchors Colorado's Front Range as a national hub for aerospace, defense, and advanced research. The metro is served by Interstate 25, Interstate 70, and Interstate 225, and spans Denver, Arapahoe, Jefferson, and Adams counties. It is home to a dense aerospace and defense cluster — including Lockheed Martin Space in Littleton, United Launch Alliance in Centennial, Ball Aerospace, and Buckley Space Force Base — alongside NIST and NREL research operations, medical device makers, and telecommunications leaders such as Lumen and DISH. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.
Because Denver sits outside our Mid-Atlantic pickup radius, we serve the Denver metro and the surrounding Arapahoe, Jefferson, and Adams county area through two intake paths: prepaid ship-in calibration with a typical five-business-day turnaround, and onsite calibration appointments at your facility. Each calibration is performed against documented procedures, traced through NIST, and accompanied by an audit-ready certificate that supports AS9100, ISO 13485, ISO 9001, and FDA 21 CFR Part 820 quality systems.
