Serving Ridgefield, CT

Ridgefield occupies the northwest corner of Fairfield County, a 35-square-mile town of about 25,000 people pressed against the New York state line, with Danbury to the north, Redding to the east, Wilton to the south, and the Westchester and Putnam County towns of North Salem, Lewisboro, and Southeast across the border. Route 7 and Route 35 carry traffic through town, Metro-North's Danbury Branch stops at Branchville, and I-84 is a short run north through Danbury. The town's measurement workload is concentrated in the Ridgebury section, where Boehringer Ingelheim's 330-acre campus at 900 Ridgebury Road serves as the company's U.S. headquarters and houses its Innovation Unit research and development center, a site of more than 2,000 employees powered entirely by renewable hydroelectric energy. Just north up Route 7 in Danbury are Linde's industrial-gas headquarters and Entegris's semiconductor-materials operation, while the surrounding Housatonic Valley towns of Bethel, Brookfield, Newtown, and Wilton add precision machining, medical device, and electronics work. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.

Our laboratory is in Gaithersburg, Maryland, and Ridgefield sits well outside our Mid-Atlantic pickup-and-delivery radius, so we serve Fairfield County and the Housatonic Valley through two intake paths: prepaid ship-in calibration with a typical five-business-day turnaround, and scheduled 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.

How Tra-Cal Serves Ridgefield, CT

In-Lab Calibration:

Send your equipment to our ANAB-accredited ISO/IEC 17025:2017 laboratory with prepaid inbound and return shipping. Calibration is performed in a climate-controlled environment against documented procedures, with traceability through NIST. Standard turnaround is approximately five business days from receipt, and asset records are retained with automated due-date notifications.

Onsite Calibration:

Our metrologists travel to Ridgefield-area facilities for fixed assets, large inventories, and instruments that should not be moved — stability chambers, ovens and freezers, environmental rooms, and fixed test benches on regulated research and production floors. Each mobile laboratory carries more than 100 reference instruments, and calibration is performed in a controlled environment at your site on a scheduled appointment, with the same accreditation, NIST traceability, and documentation as in-lab service.
