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.

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 Woodbridge, VA
Woodbridge sits in eastern Prince William County along the I-95 and U.S. Route 1 corridor, between Fort Belvoir to the north and Marine Corps Base Quantico to the south, with the Occoquan River forming its northern edge and Virginia Route 123 and the Prince William Parkway feeding its commercial core. Measurement-dependent operations here include Prince William Water’s H.L. Mooney Advanced Water Reclamation Facility on Rippon Boulevard — a 24-million-gallon-per-day plant that houses the utility’s H2O quality laboratory — the 183-bed Sentara Northern Virginia Medical Center on Opitz Boulevard, with its imaging, surgical, and clinical laboratory equipment, and Northern Virginia Community College’s Woodbridge campus, whose programs include engineering technology, HVAC and refrigeration, and data center operations. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.
Because Woodbridge sits inside our Mid-Atlantic pickup and delivery radius, we serve Prince William County and the greater Northern Virginia area through three intake paths: scheduled pickup and delivery, 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.
