In-Lab & Onsite Calibration Services in Pasadena, CA

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 Pasadena 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 Pasadena, CA

Pasadena is a major cultural, research, and technology hub in the San Gabriel Valley of northwestern Los Angeles County, positioned along the I-210, SR-134, and I-110 freeways. Its economy spans aerospace and scientific research, biotechnology and medical devices, engineering and technology firms, and precision manufacturing. Tra-Cal supports these operations with ANAB-accreditedISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.

Because Pasadena sits outside our Mid-Atlantic pickup radius, we serve the Los Angeles area through two intake paths: prepaid ship-in calibration with a typical five-business-day turnaround, and onsite calibration appointmentsat 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.
