Serving Winchester, VA
Winchester is an independent city at the northern end of the Shenandoah Valley, entirely surrounded by Frederick County and reached from Interstate 81 at Exit 315, where Virginia Route 7 — the Berryville Pike — crosses, with US 11, US 50, US 522 and the Route 37 bypass carrying traffic through the city. Measurement-dependent operations here include the 495-bed Winchester Medical Center on Amherst Street, a Level II trauma center with interventional radiology, PET-CT and clinical laboratory services; Trex Company's global headquarters and manufacturing operations on Trex Way, one of the composite decking maker's three core manufacturing locations, run from a 64,000-square-foot headquarters on eight acres beside Interstate 81; Shenandoah University's pharmacy laboratories on University Drive, equipped for HPLC, automated DNA isolation and real-time PCR; and the city's Public Utilities department, which operates the Opequon Water Reclamation Facility treating more than six million gallons of wastewater a day and the Percy D. Miller Water Treatment Plant supplying up to ten million gallons a day across more than 125 miles of pipeline. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.
Because Winchester sits inside our Mid-Atlantic pickup and delivery territory, we serve Frederick County and the northern Shenandoah Valley 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.
