In-Lab & Onsite Calibration Services in Mobile, AL

No. Tra-Cal's ISO/IEC 17025:2017, ANAB-accredited laboratory is physically located at 8577 Atlas Drive, Gaithersburg, MD 20877. Mobile and Baldwin counties are served two ways: prepaid ship-in calibration with roughly a five-business-day in-lab turnaround, and scheduled onsite visits by our mobile calibration labs. We do not maintain an office or drop-off point in Mobile and never claim one.

Austal USA on Blakeley Island and the ship-repair yards on Pinto Island run enormous inventories of torque tools, pressure gauges, micrometers, multimeters, thermal instruments and NDT support equipment, all of it on recall schedules tied to Navy and commercial survey requirements. Tra-Cal calibrates that mix to ISO/IEC 17025:2017 with NIST traceability, reports measurement uncertainties, and returns certificates that reference ANSI Z540-1 and Z540.3 for source inspection and audit review.

Yes. Each Tra-Cal mobile lab carries well over 100 reference instruments, so a technician can calibrate RF, electrical, temperature, pressure and dimensional assets in place - at an aerospace shop on the Mobile Aeroplex at Brookley, a plant along the Port of Mobile, or a facility across the bay in Daphne or Spanish Fort. Gulf Coast onsite work is booked as a planned campaign, so send an asset list and give us lead time.

No, and we would rather say so plainly. Tra-Cal's courier pickup and delivery runs cover the Mid-Atlantic around the Gaithersburg lab, and Mobile sits far outside that radius. Gulf Coast customers use prepaid ship-in service, where we cover freight in both directions, or an onsite mobile-lab visit. Nothing about our Mobile service depends on a local facility.

Standard in-lab turnaround is about five business days from receipt, plus transit each way between the Gulf Coast and Maryland. Expedited handling is available when a vessel delivery milestone, an aircraft return-to-service date or a customer audit is driving the schedule. A dedicated account manager confirms receipt, flags anything found out of tolerance before work proceeds, and commits to a return date.

We ship to and visit the full Mobile metro: Mobile ZIP codes 36602 through 36619 plus 36693 and 36695, Prichard 36610, Chickasaw 36611, Saraland 36571, Satsuma 36572, Theodore 36582, Semmes 36575, and across Mobile Bay to Daphne 36526, Spanish Fort 36527 and Fairhope 36532. Coverage is defined by shipping and scheduling, not by any local storefront.

Tra-Cal is accredited to ISO/IEC 17025:2017 by ANAB. Our current scope of accreditation is published as a PDF on this site so Mobile-area quality managers can verify parameters and ranges before shipping assets. Calibrations are NIST-traceable and support AS9100, ISO 13485, ISO 9001 and FDA 21 CFR Part 820 quality systems.

RF and microwave, general electronic, temperature and humidity, physical and dimensional, oven and freezer, optical, and timing and frequency instrumentation - the mix an aircraft final assembly line, an MRO hangar, a piston-engine manufacturer, a steel mill or a chemical plant along the Mobile River actually runs. We also repair equipment from more than 100 manufacturers and sell new instruments, so a failed asset does not have to become a purchase decision.
