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 region wraps around the inland waters from Olympia north to Everett, linking King, Pierce, Snohomish, and Kitsap counties along I-5, I-405, and SR 167. It forms a deep aerospace, marine, and defense manufacturing corridor, anchored by Boeing's widebody plant at Paine Field, the 737 final assembly line in Renton, and the machine shops of the Kent Valley. Add Naval Base Kitsap and Puget Sound Naval Shipyard at Bremerton, Joint Base Lewis-McChord, and electronics, space, and medical device firms from Redmond to Fife.
Such work depends on RF analyzers, pressure instruments, torque tools, thermocouples, and environmental chambers. Washington sits far outside our pickup radius, so choose prepaid ship-in or onsite calibration appointments, documented with ANAB-accredited, NIST traceable certificates.

How Tra-Cal Serves the Puget Sound, WA
In-Lab Calibration:
Send your equipment to our ANAB-accredited ISO/IEC 17025:2017 laboratory with prepaid inbound and return shipping. Calibration is performed in a climate-controlled environment against documented procedures, with traceability through NIST. Standard turnaround is approximately five business days from receipt, and asset records are retained with automated due-date notifications.
Onsite Calibration:
Our metrologists travel to Puget Sound-area facilities for fixed assets, large inventories, and instruments that should not be moved. Calibration is performed in a controlled environment at your site on a scheduled appointment, with the same accreditation, NIST traceability, and documentation as in-lab service.
