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.

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 Tacoma, WA

Tacoma is the Pierce County seat and sits on Commencement Bay, where Interstate 5, Interstate 705, SR 7, SR 16 and SR 509 converge and the Thea Foss, Blair and Hylebos waterways cut into the Tideflats industrial district. The Port of Tacoma, founded in 1918, owns close to 2,500 acres there and runs five major container terminals, with the federal Blair Waterway channel at 51 feet below mean lower low water and scheduled to be deepened to 57 feet. U.S. Oil and Refining operates a 42,000 barrel per day refinery with 2.9 million barrels of storage on the same tideflats, Tacoma Public Utilities has been publicly owned since 1893 and runs 49 distribution substations and a Green River supply rated to 150 million gallons a day, and MultiCare Tacoma General carries 367 licensed beds as a Level II adult trauma center. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.

Because Tacoma sits outside our Mid-Atlantic pickup radius, we serve Pierce County 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.
