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 Redmond, WA
Redmond incorporated in 1912 and sits in King County with no interstate highway inside its limits. SR 520 carries traffic west toward Bellevue and Seattle, SR 202 and SR 908 handle the local arterial load, and three Link 2 Line stations now serve the city at Downtown Redmond, Marymoor Village and Redmond Technology. The Willows Road corridor is a precision hardware cluster. Aerojet Rocketdyne builds in-space electric propulsion in Redmond and performed functional testing and magnetic field mapping there on the NASA Advanced Electric Propulsion System Hall thruster, Physio-Control manufactures defibrillators and patient monitoring equipment on Willows Road, B.E. Meyers runs three laser-safe test tunnels with thermal cycle testing and diode characterization, EOSPACE builds lithium niobate electro-optic modulators with switch settling under one microsecond, Laser Techniques Company supplies laser bore and weld inspection systems, and Paroscientific makes Digiquartz resonant quartz pressure sensors on 148th Avenue NE. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.
Because Redmond sits outside our Mid-Atlantic pickup radius, we serve King 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.
