In-Lab & Onsite Calibration Services in Yuma, AZ

No. Tra-Cal's ISO/IEC 17025:2017 accredited laboratory is physically located at 8577 Atlas Drive, Gaithersburg, MD 20877. Yuma and the surrounding Yuma County communities are served two ways: prepaid ship-in calibration with a typical five-business-day turnaround in the lab, and scheduled onsite calibration using Tra-Cal's mobile laboratories. Southwest Arizona is far outside the Mid-Atlantic pickup-and-delivery radius, so there is no local courier route — but the accreditation scope and the certificate are identical regardless of where your equipment ships from.

Tra-Cal issues a prepaid shipping label, your team packs the instruments, and the lab handles freight in both directions. Typical turnaround is about five business days in the lab once the equipment arrives. Every item returns with a NIST-traceable certificate of calibration, as-found and as-left data where applicable, and a record of any adjustments. For instruments on a fixed recall cycle, a dedicated account manager can stage shipments against your due dates so test equipment is not idle during a test window.

Tra-Cal is accredited to ISO/IEC 17025:2017 by ANAB. Measurements are NIST-traceable, and the lab's procedures reference ANSI/NCSL Z540-1 and Z540.3 for calibration system and measurement-decision-risk requirements. The current scope of accreditation is published on the Tra-Cal site, so quality and contracts staff can confirm a specific parameter and range is covered before anything ships.

Tra-Cal covers RF and microwave, electronic, temperature and humidity, physical and dimensional, optical, and timing and frequency disciplines. In practice that means spectrum analyzers, network analyzers, signal generators, RF power meters, oscilloscopes, frequency counters, data acquisition and telemetry instrumentation, pressure and torque devices, gage blocks and calipers, thermocouples, and environmental chambers. That range lines up with the instrumentation behind range telemetry, munitions and armament testing, and desert environmental testing in Yuma County.

Yes, for scheduled campaigns. Tra-Cal's mobile laboratories carry more than 100 reference instruments per van, so a large block of assets can be calibrated in place rather than shipped. Because Yuma is roughly 2,400 road miles from the Gaithersburg lab, onsite visits to southwest Arizona are arranged well in advance and generally make sense when the asset count justifies the trip. For smaller quantities, prepaid ship-in is faster and more economical. Access and escort requirements for work performed on a military installation are coordinated through the sponsoring organization.

Tra-Cal supports customers across Yuma County in southwest Arizona, including Yuma itself (ZIP codes 85364, 85365, 85367 and 85369), plus Somerton, San Luis, Wellton, Fortuna Foothills, and the Yuma Proving Ground area in northern Yuma County and southwestern La Paz County. Because the service model is prepaid ship-in, coverage is not limited by distance from any particular ZIP code.

Yes. Temperature and humidity is one of Tra-Cal's accredited disciplines, along with oven and freezer chamber calibration and mapping. This is directly relevant in Yuma, which is the driest and sunniest populated place in the contiguous United States and has recorded temperatures as high as 124 degrees Fahrenheit — conditions that make it a natural site for hot-environment testing and that place real demands on the sensors, data loggers, and chambers used to characterize it.

Call +1-301-527-9200 or email info@tra-cal.com with a list of manufacturers, models, and quantities, plus any accreditation or turnaround requirements tied to your contract. Tra-Cal has been calibrating test and measurement equipment for more than 35 years, is veteran-owned, and can also handle repair across 100-plus manufacturers if an instrument arrives out of tolerance and needs work before it can be certified.
