In-Lab & Onsite Calibration Services in Chester, PA
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 Chester 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 Chester, PA
Chester sits in Delaware County within Greater Philadelphia (the Delaware Valley), and our team regularly supports quality and calibration programs for organizations in Chester and neighboring communities such as Eddystone, Brookhaven, Upland, Marcus Hook, Trainer, and Ridley Park. The area’s manufacturing, energy and utilities, healthcare, and logistics and distribution operations depend on measurement equipment that stays accurate and audit-ready, and our ANAB-accredited ISO/IEC 17025:2017 lab delivers NIST-traceable calibrations with fast, reliable turnaround.
Because Chester sits outside our Mid-Atlantic pickup radius, we serve Greater Philadelphia 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.
