Serving Andover, MA

Andover sits in Essex County at the center of the Merrimack Valley, where Interstate 93 and Interstate 495 cross and Routes 28, 125, and 133 link the town to Lawrence, North Andover, Methuen, Tewksbury, and Wilmington. For a town of roughly 36,000 people it carries an unusually dense instrumentation base. Raytheon’s Andover plant is the town’s largest private employer and a principal build site for Patriot air and missile defense hardware. Mercury Systems keeps its corporate headquarters for aerospace and defense electronics on Minuteman Road, MKS builds vacuum, pressure, and process-control instrumentation on Tech Drive, and Vicor designs power conversion modules a short distance away. On the life-sciences side, Pfizer’s 70-acre Andover campus is one of the largest biotherapeutic and vaccine manufacturing sites in the industry. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.

Because Andover sits well outside our Mid-Atlantic pickup and delivery radius, we serve the Merrimack Valley 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.
