Serving Port Arthur, TX

Port Arthur sits on Sabine Lake in Jefferson County, southeast of Beaumont, with State Highway 87 running through the city and the Rainbow Bridge crossing the Neches River to the west. Incorporated in 1898 as the southern terminus of Arthur Stilwell's railroad, the city turned to refining after the 1901 Spindletop discovery. Motiva's Port Arthur Manufacturing Complex, Valero's refinery, TotalEnergies, BASF and the Port of Port Arthur anchor the industrial base, and Lamar State College Port Arthur trains instrumentation and process technicians. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.

Because Port Arthur sits outside our Mid-Atlantic pickup radius, we serve Jefferson County and the wider Southeast Texas Gulf Coast 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.
