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 Waltham 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 Waltham, MA

Waltham sits on the Charles River in Middlesex County about nine miles west of downtown Boston, with I-95/Route 128 running along its western edge. Precision measurement is Waltham's oldest trade: the Waltham Watch Company opened here in 1854 as the first to build watches on an assembly line, earning the city its Watch City name, and Raytheon developed mass-production magnetron tubes here during the Second World War. The Route 128 belt became the Northeast's original technology corridor, and today Thermo Fisher Scientific and Revvity both run their global headquarters here alongside RTX (Raytheon), Alkermes, PAREXEL, Boston Dynamics, and Pegasystems, with Brandeis and Bentley universities adding research laboratories. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.

We serve the Route 128 corridor two ways: prepaid ship-in calibration with a typical five-business-day turnaround, and onsite calibration appointments at your facility. Every calibration is NIST-traceable and comes with an audit-ready certificate supporting AS9100, ISO 13485, ISO 9001, and FDA 21 CFR Part 820 quality systems.
