In-Lab & Onsite Calibration Services in the Puget Sound, WA
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 Puget Sound 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 the Puget Sound, WA
The Puget Sound is the inland sea of the Salish Sea, stretching from Olympia north to Everett and ringed by the Seattle–Tacoma metro and the Kitsap Peninsula in the Puget Sound Lowlands of Western Washington. From aerospace and defense manufacturers to maritime and shipbuilding operations, electronics and technology-hardware teams, and precision machining shops across Seattle, Tacoma, Everett, Bellevue, Bremerton, Olympia, and Renton, operations throughout the region depend on accurate, traceable measurements. As an ANAB-accredited ISO/IEC 17025:2017 calibration laboratory, Tra-Cal delivers NIST-traceable certificates that hold up to the most rigorous audits.
Serving the Puget Sound works three ways: ship your instruments to our Maryland lab, arrange scheduled pickup and return delivery across the region, or book onsite calibration appointments for fixed assets and large inventories. Whichever path fits your workflow, you get the same accreditation, the same NIST-traceable standards, and the same documentation.

How Tra-Cal Serves the Puget Sound, WA
In-Lab Calibration:
In-lab calibration is the core of our service. Instruments are shipped to our ISO/IEC 17025:2017 laboratory, calibrated under controlled conditions, and returned with full NIST-traceable documentation. It is the most cost-effective option for portable instruments and bench equipment used by teams across the Puget Sound region.
Onsite Calibration:
For instruments that cannot leave your floor, our metrologists travel to Puget Sound-area facilities to perform onsite calibration. We handle fixed assets, large inventories, and sensitive equipment in place, with the same NIST-traceable rigor and documentation you would receive in our lab.
