In-Lab & Onsite Calibration Services in Charleston, WV

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 Charleston 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 Charleston, WV

Charleston is the capital and most populous city of West Virginia, seated at the confluence of the Elk and Kanawha rivers in Kanawha County. The Kanawha Valley is served by Interstate 64, Interstate 77, and Interstate 79, along with US 60 and US 119, connecting Charleston to neighboring communities such as South Charleston, Dunbar, St. Albans, Nitro, and Cross Lanes. The area supports chemical manufacturing, energy production, healthcare, and public-sector operations. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.

Because Charleston sits outside our Mid-Atlantic pickup radius, we serve the Kanawha Valley 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.
