In-Lab & Onsite Calibration Services in Ann Arbor, MI
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 Ann Arbor 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 Ann Arbor, MI
Ann Arbor is the seat of Washtenaw County, sitting where Interstate 94, US-23, and M-14 converge about 40 miles west of Detroit. It is one of the country’s densest research and advanced-engineering markets: the University of Michigan reported a record $2.04 billion in research volume in fiscal year 2024, and its North Campus hosts Mcity, a 32-acre outdoor connected-and-automated-vehicle proving ground with more than 16 acres of instrumented roads and traffic infrastructure. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.
Because Ann Arbor sits roughly 500 road miles from our Gaithersburg, Maryland laboratory, well outside our Mid-Atlantic pickup and delivery radius, we serve Washtenaw County through prepaid ship-in calibration with a typical five-business-day turnaround, and onsite calibration appointments at your facility. Each calibration is traced through NIST and accompanied by an audit-ready certificate supporting AS9100, ISO 13485, ISO 9001, and FDA 21 CFR Part 820.

Standard turnaround is approximately five business days from receipt, and asset records are retained with automated due-date notifications.
Onsite Calibration:

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.
