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 Oak Harbor, WA

Oak Harbor is an incorporated city on Whidbey Island in Island County, and SR 20 is the only state route inside the city limits. No interstate highway touches the island, so instruments reach the mainland either across the 1935 Deception Pass and Canoe Pass bridges or by ferry, which makes calibration scheduling a logistics question before it is a measurement question. Naval Air Station Whidbey Island, commissioned in 1942, operates Ault Field and the Seaplane Base and hosts the Navy EA-18G Growler electronic attack wing and its P-8A Poseidon patrol and reconnaissance wing. IDEX Health and Science builds precision fluidic components for analytical instrumentation on Oak Street, the city Clean Water Facility at Windjammer Park handles all of Oak Harbor wastewater with its own staff lab chemist, and Skagit Valley College teaches at its Whidbey Island campus on SE Pioneer Way. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.

Because Oak Harbor sits outside our Mid-Atlantic pickup radius, we serve Island County and Whidbey Island 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.
