Serving Merrimack, NH
Merrimack sits in Hillsborough County along the Merrimack and Souhegan rivers, strung between Nashua and Manchester on the F.E. Everett Turnpike, with Daniel Webster Highway (U.S. Route 3), Route 101A, and the Continental Boulevard industrial corridor carrying most of the town’s commercial traffic. Its anchor for precision measurement work is Elbit Systems of America’s Kollsman operation at 220 Daniel Webster Highway, which has designed and built altimeters, cockpit displays, enhanced vision systems, and electro-optical assemblies here for decades. Around it sit Fidelity Investments’ Merrimack campus, PC Connection’s headquarters on Milford Road, the Anheuser-Busch brewery, and — minutes down Route 3 — the BAE Systems electronic warfare campuses in Nashua and Hudson, New Hampshire’s largest defense employer. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.
Because Merrimack sits well outside our Mid-Atlantic pickup radius, we serve southern New Hampshire 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.
