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 Dalles, OR

The Dalles is the seat of Wasco County and the largest Oregon city on the Columbia River outside metro Portland, sitting at the eastern edge of the Columbia River Gorge National Scenic Area where Interstate 84, U.S. 30, and U.S. 197 converge. For a city of roughly 16,000 people, the measurement load here is unusually heavy: The Dalles Lock and Dam — the U.S. Army Corps of Engineers project two miles upriver, with 22 turbines and about 1,878 megawatts of installed capacity — and the Bonneville Power Administration’s Celilo Converter Station, northern terminus of the Pacific DC Intertie, keep high-voltage, power-quality, and protective-relay instrumentation in constant use. Google’s Columbia River data center campus, the renewable-energy and wind-technician programs at Columbia Gorge Community College, Adventist Health Columbia Gorge, and the fruit-processing lines at Oregon Cherry Growers and Orchard View Farms add data-center, biomedical, and process-temperature work, while the unmanned-aircraft engineering cluster around Bingen and Dallesport sits minutes across the river. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.

Because The Dalles sits well outside our Mid-Atlantic pickup radius, we serve the Mid-Columbia region from our Gaithersburg, MD laboratory through two intake paths: prepaid ship-in calibration with a typical five-business-day turnaround, and onsite calibration appointmentsat 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.
