In-Lab & Onsite Calibration Services in Bellevue, NE

No. Tra-Cal's ISO/IEC 17025:2017, ANAB-accredited laboratory is physically located at 8577 Atlas Drive in Gaithersburg, Maryland. We serve Bellevue and Sarpy County two ways: prepaid ship-in service to the Gaithersburg lab, and scheduled onsite calibration using our mobile labs. Nebraska is outside our Mid-Atlantic pickup and delivery radius, so there is no local courier route - most Bellevue customers use prepaid ship-in, and onsite visits are arranged in advance.

Yes. Offutt sits immediately adjacent to Bellevue in Sarpy County and is the headquarters of U.S. Strategic Command, the 557th Weather Wing and the 55th Wing, which serves as the host unit under Air Combat Command. Contractors and suppliers supporting those missions generally need documented measurement traceability, and our accreditation program references ANSI Z540-1 and Z540.3 with NIST traceability throughout. Every certificate documents standards used, the traceability chain, environmental conditions, as-found and as-left data, and measurement uncertainty where applicable. To be clear, Tra-Cal works with contractors and suppliers; we make no claim about work performed for the base itself.

Yes, and it is one of our core disciplines. The RC-135 fleet is permanently based at Offutt and operated by the 55th Wing using forward operating locations worldwide, and the 55th Operations Group flies 46 aircraft across 13 models of seven different types - the most diverse fleet in Air Combat Command. Suppliers supporting airborne signals intelligence, antenna and receiver systems, and secure command and control carry spectrum analyzers, signal generators, power meters, noise figure analyzers, network analyzers and attenuator standards. We calibrate that class of equipment with RF capability extending to 50 GHz, plus timing and frequency work on precision oscillators and frequency references.

Yes. The 557th Weather Wing at Offutt is the Air Force's lead military meteorology center, with more than 1,800 active-duty, reserve, civilian and contract personnel generating forecast, climatological and space weather products worldwide. Suppliers and support operations in that field run temperature probes, humidity sensors, barometric and differential pressure transducers, anemometers and data loggers. Temperature and humidity calibration is a core part of our accredited scope, and we perform it against documented procedures with NIST-traceable references.

Yes. Our mobile labs carry more than 100 reference standards per van and can cover a large share of a typical calibration list at your facility. Onsite service is the practical choice for aircraft ground support equipment, torque and pressure tooling, hydraulic test stands, and bench instrumentation that cannot leave a controlled or secure area. Because Nebraska falls outside our regional radius, onsite trips are scheduled in advance and are most economical when several assets or several nearby Sarpy County sites are covered in a single visit.

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. Everything returns with NIST-traceable certificates issued under our ISO/IEC 17025:2017 accreditation. Bellevue sits on U.S. Route 75 at the eastern terminus of Nebraska Highway 370, minutes from the Interstate 80 and Interstate 29 corridors, so outbound freight from Sarpy County moves quickly.

We serve the Bellevue ZIP codes 68005 and 68123, covering the city from the Missouri River bluffs west toward Papillion, along with the Offutt Air Force Base area and La Platte. We also serve the wider Sarpy County region - the third most populous county in Nebraska, with roughly 190,600 residents at the 2020 census - including Papillion, La Vista, Gretna and Springfield.

Call +1-301-527-9200 or email info@tra-cal.com with a list of your instruments - manufacturer, model, quantity and any special requirements, including whether ANSI Z540.3 or AS9100 documentation is needed. We will return a written quote with pricing and turnaround, and recommend whether ship-in or an onsite visit is the better fit. A dedicated account manager stays with your account, and our asset database management keeps calibration history and due dates in one place. Tra-Cal is a veteran-owned lab with more than 35 years in test and measurement calibration.
