In-Lab & Onsite Calibration Services in Little Rock, AR
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 Little Rock 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 Little Rock, AR
Little Rock is the seat of Pulaski County and the center of Arkansas government and industry, crossed by Interstates 30 and 630, with I-40 along the north bank, US 65 and US 167 feeding in, and ZIP codes running from 72201 out to 72223. Measurement-heavy work concentrates at Little Rock Air Force Base in Jacksonville, where the 19th Airlift Wing flies C-130J missions and the 314th trains C-130 aircrew. In the city, Dassault Falcon Jet runs its completion center and Dassault Aircraft Services, installing avionics, interiors, and paint. Camp Robinson hosts the National Guard Professional Education Center, and UAMS anchors clinical and laboratory research.
Because Little Rock sits outside our Mid-Atlantic pickup radius, we serve central Arkansas two ways: prepaid ship-in calibration with a typical five-business-day turnaround, and onsite calibration appointments. Our ANAB-accredited ISO/IEC 17025:2017 calibration is NIST-traceable, with audit-ready certificates supporting AS9100, ISO 13485, ISO 9001, and FDA 21 CFR Part 820.

How Tra-Cal Serves Little Rock, AR
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 Little Rock-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.
