In-Lab & Onsite Calibration Services in Tewksbury, MA
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 Tewksbury and the Merrimack Valley 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.

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 Tewksbury, MA
Tewksbury sits in Middlesex County about 19 miles north-northwest of Boston, where Interstate 93 and Interstate 495 frame the town and Routes 38, 133, and 129 link it to Lowell, Andover, Billerica, and Wilmington. The Merrimack River forms its northern edge, and the Shawsheen and Concord Rivers cut through the south and west. For a town of roughly 31,000 people it carries an unusually heavy instrumentation load. Raytheon, an RTX business, has run a defense electronics campus on Apple Hill Drive here for decades, and the surrounding belt adds Textron Systems and Analog Devices in Wilmington, the Raytheon and Pfizer complexes in Andover, and UMass Lowell research labs four miles up Route 38. Tewksbury Hospital, the state Department of Public Health campus on East Street, maintains its own regulated temperature and clinical equipment, and Market Basket headquarters adds refrigeration and weighing systems across its distribution network. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.
Because Tewksbury sits well outside our Mid-Atlantic pickup and delivery radius, we serve Middlesex County and 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.

How Tra-Cal Serves Tewksbury, MA
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 Tewksbury-area facilities for fixed assets, large inventories, and instruments that should not be moved. 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.
Frequently Asked Questions
-
Yes. Tra-Cal’s laboratory is at 8577 Atlas Drive in Gaithersburg, MD, and Tewksbury sits well outside our Mid-Atlantic pickup and delivery radius, so we serve Middlesex County through two intake paths: prepaid ship-in calibration with a typical five-business-day turnaround, and scheduled onsite calibration at your facility. The same ISO/IEC 17025:2017 accreditation, NIST-traceable standards, and certificate format apply either way.
-
Yes. Tra-Cal maintains ISO/IEC 17025:2017 accreditation through ANAB, the ANSI National Accreditation Board. ANSI/NCSL Z540-1 and Z540.3 conformance is also available. The current scope of accreditation is published on the Tra-Cal Certificate of Accreditation page.
-
Standard turnaround for in-lab calibration is approximately five business days from receipt, plus transit each way between Tewksbury and Gaithersburg, MD. Expedited turnaround is available on request and depends on instrument type, parameter scope, and current lab volume, which matters when a program milestone or a scheduled audit at a Tewksbury site cannot move.
-
Yes. Each calibration certificate documents traceability through NIST, includes as-found and as-left data where applicable, lists the standards used, the calibration procedure reference, environmental conditions, and the technician. Certificates are designed to support AS9100, ISO 13485, ISO 9001, and FDA 21 CFR Part 820 quality system audits.
-
Tra-Cal supports defense electronics and radar engineering teams, contract and precision manufacturers, RF and microwave labs, medical device and life-sciences groups, healthcare and public-health facilities, and university research groups across Tewksbury, Lowell, Billerica, Wilmington, Andover, Dracut, and Chelmsford.
-
Yes. Onsite calibration is available for fixed assets, large inventories, and instruments that should not be transported. Our mobile labs carry more than 100 reference instruments per van, which covers most electronic, temperature, humidity, physical, and dimensional workloads at Tewksbury facilities along Apple Hill Drive, Ballardvale Street, and the Route 38 and Route 133 corridors. Appointments are scheduled in advance with your team.
-
A packaging guide is provided when you request a quote. In general, instruments should be powered down, accessories included where required for calibration, and packed with appropriate cushioning. A prepaid shipping label is available for qualifying customers, so nothing leaves your Tewksbury dock without a tracked, insured route to the lab.
-
Yes. Tra-Cal offers metrology database management with automated due-date notifications, historical certificate retrieval, and asset-level records suitable for audit support.
