In-Lab & Onsite Calibration Services in Raleigh, NC

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 Raleigh 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 Raleigh, NC

Raleigh is the capital of North Carolina and the seat of Wake County, anchoring the Research Triangle alongside Durham and Chapel Hill. The city and its neighbors—Cary, Morrisville, Apex, Garner, and Wake Forest—are connected by I-40, I-440, the I-540 outer loop, US-1, US-70, and US-401, giving our logistics team dependable access across the region. Raleigh’s economy spans state government, the technology and research employers of Research Triangle Park, biotechnology and pharmaceutical firms, higher education anchored by NC State University, and a growing healthcare sector—all environments where accurate, traceable measurement is essential. As an ANAB-accredited ISO/IEC 17025:2017 laboratory, Tra-Cal supports these Raleigh-area teams with NIST-traceable calibration and audit-ready certificates.

Because Raleigh sits outside our Mid-Atlantic pickup radius, we serve the Research Triangle 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.
