Serving Prescott, AZ
Prescott is the Yavapai County seat, sitting at about 5,000 feet with SR 89 and SR 69 as the only state routes into the city and no interstate or US route at all. The FAA describes Prescott Regional Airport, Ernest A. Love Field, as one of the nation fifty busiest airports because of intensive fixed wing and helicopter flight training, which drives a continuous avionics and test equipment cycle. Chelton Avionics manufactures and repairs avionics on Wilkinson Drive, including RT-5000 radios for Coast Guard MH-60T aircraft under federal contract. Sturm, Ruger and Company runs roughly 230,000 square feet of firearms manufacturing on Ruger Road with enclosed test ranges on site, Yavapai College teaches Electrical and Instrumentation Technology and CNC machining at its Career and Technical Education Center across the street, and the city operates seven production wells under an ADEQ-approved arsenic blending plan plus a 6.0 MGD and a 4.75 MGD water reclamation plant serving 26,089 connections. The Bob Stump VA Medical Center runs its clinical laboratory around the clock on Highway 89 North. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.
Because Prescott sits outside our Mid-Atlantic pickup radius, we serve Yavapai County 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, 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.
