In-Lab & Onsite Calibration Services in Seymour, CT
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 Seymour 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 Seymour, CT
Seymour sits in the lower Naugatuck River Valley of New Haven County, Connecticut, part of the historic “Valley” manufacturing corridor alongside Ansonia, Derby, and Shelton. The region has a long precision-manufacturing tradition — from copper and wire-and-cable production to today’s aerospace-components, precision-machining, and electronics manufacturers serving defense and commercial customers. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.
Because Seymour sits outside our Mid-Atlantic pickup radius, we serve the region 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 and returned with a NIST-traceable certificate that supports your AS9100, ISO 13485, ISO 9001, and FDA 21 CFR Part 820 compliance requirements.
