In-Lab & Onsite Calibration Services in Marietta, OH
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 Marietta and Mid-Ohio 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. 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 Marietta, OH
Marietta sits at the confluence of the Muskingum and Ohio Rivers in Washington County, roughly eleven miles northeast of Parkersburg, West Virginia, reached from Interstate 77 along the city’s eastern edge and from State Routes 7, 60, 26, 550, and 676. As the county seat and the principal city of the Marietta micropolitan area, it anchors an Ohio River industrial corridor that traces back to the first oil wells drilled in the region in 1860. Eramet Marietta operates the longest-running ferromanganese refinery in North America here; Sewah Studios has cast historical markers in the city since 1927; and Chemours Washington Works, a 1,200-acre fluoropolymer plant supplying semiconductor, automotive, and healthcare markets, runs a short distance downriver near Parkersburg. The petroleum engineering and geology program at Marietta College, the technical labs at Washington State Community College, and Marcellus and Utica shale gas and midstream operations across Washington County add further instrumentation demand. Tra-Cal provides ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment to organizations working in this environment.
Our laboratory is physically located at 8577 Atlas Drive in Gaithersburg, Maryland; we do not operate an office in Marietta. Because southeastern Ohio sits well outside our Mid-Atlantic pickup and delivery radius, we serve Marietta through two intake paths: prepaid ship-in calibration with a typical five-business-day turnaround, and scheduled onsite calibration appointments at your facility using our mobile laboratories, which carry more than 100 instruments per van. 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 Marietta, OH
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 Marietta-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 supports Marietta and Washington County through two intake paths: prepaid ship-in service with a typical five-business-day turnaround, and scheduled onsite calibration appointments at your facility using our mobile laboratories. Southeastern Ohio sits outside our Mid-Atlantic pickup and delivery radius, so those are the two paths available — but the same ISO/IEC 17025:2017 ANAB accreditation, NIST traceability, documented procedures, and certificate format apply either way.
-
Yes. Tra-Cal maintains ISO/IEC 17025:2017 accreditation. 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 of the instrument. Expedited turnaround is available on request and depends on instrument type, parameter scope, and current lab volume.
-

Tra-Cal supports ferroalloy and metals refining, specialty and fluoropolymer chemical production, oil and gas and midstream operations in the Marcellus and Utica plays, plastics and industrial manufacturing, power generation, healthcare and clinical facilities, and college and community-college teaching and research labs.

-
Yes. Our mobile laboratories travel to Marietta and the wider Mid-Ohio Valley on a scheduled appointment, which suits fixed assets, large instrument inventories, refinery and plant floor equipment, and anything that should not be shipped. Each van carries more than 100 reference instruments, and the calibration is performed in a controlled environment at your facility with the same ANAB-accredited ISO/IEC 17025:2017 scope, NIST traceability, and documentation as in-lab work.
