In-Lab & Onsite Calibration Services in Great Falls, MT

No. Tra-Cal's ISO/IEC 17025:2017, ANAB-accredited laboratory is physically located at 8577 Atlas Drive in Gaithersburg, Maryland. We serve Great Falls and Cascade County two ways: prepaid ship-in service to the Gaithersburg lab, and scheduled onsite calibration using our mobile labs. Great Falls is well outside our Mid-Atlantic pickup and delivery radius, so we do not run a local courier route to Montana - most Great Falls customers use prepaid ship-in, and onsite visits are arranged in advance.

You request a quote, we send a prepaid shipping label and packing guidance, and you ship your instruments to Gaithersburg. Typical turnaround is about five business days in the lab, plus transit each way from Montana. Every item comes back with NIST-traceable certificates issued under our ISO/IEC 17025:2017 accreditation. For shops along the Interstate 15 corridor and the Great Falls International Airport industrial area, batching several assets into one shipment keeps freight cost per instrument low.

Yes. Our mobile labs carry more than 100 reference standards per van and can perform a large share of a typical calibration list at your facility. Onsite work makes the most sense for Great Falls operations where equipment is fixed in place or cannot leave the site - refinery instrumentation, hydroelectric powerhouse gear, ag processing lines, or shop-floor test benches. Because Montana is outside our regional radius, onsite trips are scheduled in advance and are most economical when several assets or several nearby sites are covered in one visit.

Yes. We routinely support defense and aerospace suppliers, and our accreditation program references ANSI Z540-1 and Z540.3 with NIST traceability throughout. Malmstrom AFB hosts the 341st Missile Wing under Air Force Global Strike Command, the largest of the three Minuteman III complexes, plus the 819th and 219th RED HORSE squadrons. Contractors supporting those missions, the 120th Airlift Wing at Great Falls International Airport, or the Army Reserve units based there typically need documented traceability, and that is exactly what our certificates provide. Note that Tra-Cal works with contractors and suppliers; we are not making any claim about work performed for the base itself.

Our scope covers RF and microwave, general electronic, temperature and humidity, physical and dimensional, oven and freezer mapping, optical, and timing and frequency. That maps well onto the Great Falls mix: torque wrenches and pressure gauges from heavy construction and civil engineering units, process transmitters and gas detection from Calumet Montana Refining, electrical test sets and high-voltage instruments from the Missouri River hydroelectric plants, and thermometers and scales from specialty milling and food processing operations. We also repair instruments from more than 100 manufacturers and sell new equipment.

We serve the Great Falls ZIP codes 59401, 59402, 59403, 59404, 59405 and 59406, which covers the city, the Malmstrom AFB area and the surrounding Cascade County communities. That includes Black Eagle, Belt, Cascade, Fort Shaw, Gibson Flats, Sand Coulee, Simms, Sun Prairie, Sun River, Ulm, Vaughn, Monarch and Neihart. Because Great Falls is the economic hub for most of north-central Montana, we also handle ship-in work from smaller towns well beyond the county line.

Our ISO/IEC 17025:2017, ANAB-accredited certificates are written to satisfy the measurement traceability clauses auditors look for under AS9100, ISO 13485, ISO 9001 and FDA 21 CFR Part 820. Each certificate documents standards used, traceability chain, environmental conditions, as-found and as-left data, and measurement uncertainty where applicable. We also provide asset database management so a Great Falls quality manager can pull a complete calibration history and due-date report without rebuilding records from paper files.

Call +1-301-527-9200 or email info@tra-cal.com with a list of your instruments - manufacturer, model, quantity and any special requirements. We will return a written quote with pricing and turnaround, and recommend whether ship-in or an onsite visit fits your situation better. A dedicated account manager handles your account from that point on, so you are not re-explaining your equipment list on every cycle. Tra-Cal is a veteran-owned lab with more than 35 years in test and measurement calibration.
