In-Lab & Onsite Calibration Services in Tempe, AZ

No. Tra-Cal's laboratory is physically located at 8577 Atlas Drive, Gaithersburg, MD 20877, and we do not maintain an office or drop-off counter anywhere in Maricopa County. Tempe customers are served two ways: prepaid ship-in calibration with a typical five-business-day turnaround in our Gaithersburg lab, and scheduled onsite mobile-lab visits for workloads large enough to justify the trip. Every certificate is issued under our ISO/IEC 17025:2017, ANAB-accredited scope regardless of which path you use.

You send an asset list and we return a quote and a prepaid shipping label. You pack the instruments, we receive them in Gaithersburg, and the typical turnaround is about five business days in the lab plus transit. Certificates are NIST-traceable and delivered electronically, and we can hold your asset records in our database so the next recall cycle is a one-click reorder. This is the most common path for engineering groups around ASU Research Park, the Rio Salado corridor, and the office and light-industrial parks along South Rockford Drive and West Fairmont Drive.

Yes. Our mobile labs carry the standards to calibrate more than 100 instruments per van, which lets us work in place instead of pulling equipment out of a production or test area. Because Tempe sits well outside our Mid-Atlantic pickup-and-delivery radius, onsite visits to Maricopa County are scheduled trips rather than routine local runs. They make the most economic sense when a site has a substantial consolidated workload, or when several facilities across Tempe, Chandler, Mesa, and Phoenix can be grouped into one visit.

Tra-Cal is accredited to ISO/IEC 17025:2017 by ANAB. Our procedures reference ANSI Z540-1 and ANSI/NCSL Z540.3, all measurements are traceable to NIST, and our documentation supports customer quality systems built around AS9100, ISO 13485, ISO 9001, and FDA 21 CFR Part 820. Our current certificate and scope of accreditation are published on this site so your quality group can verify the specific parameters and uncertainties before you ship.

Our scope covers RF and microwave instrumentation such as spectrum analyzers, vector network analyzers, signal generators, and power sensors; general electronic test equipment including digital multimeters, oscilloscopes, calibrators, and DC and AC sources; temperature and humidity work covering probes, data loggers, thermal chambers, ovens, and freezers; physical and dimensional metrology including torque tools, pressure gauges, micrometers, calipers, and gage blocks; optical instrumentation; and timing and frequency standards. That mix maps directly onto what semiconductor packaging and test, electronics manufacturing services, photovoltaic, and university research operations in Tempe actually run.

We serve all of Tempe, including ZIP codes 85281, 85282, 85283, 85284, 85287, and 85288, with 85287 covering the Arizona State University campus itself. Because the service model is ship-in and scheduled onsite rather than a local branch, coverage extends across the surrounding East Valley without any change in price or process, including Chandler to the south, Mesa to the east, Scottsdale to the north, and Phoenix and Guadalupe to the west.

Plan on roughly five business days in the lab for standard ship-in work, plus ground transit each direction between Arizona and Maryland. Expedited service is available when a chamber qualification, a customer audit, or a production hold cannot wait. Each account gets a dedicated account manager, so you have one person tracking where your instruments are rather than a general support queue.

Yes. Tra-Cal repairs test and measurement equipment from more than 100 manufacturers and also sells new and refurbished instruments. For a shipped-in asset that arrives out of tolerance, this matters: we can quote and perform the repair while the unit is already in the lab, then calibrate it and ship it back on a single trip, instead of sending it to Tempe untouched and asking you to pay freight twice.
