Calibration Services

Unlike most suppliers of food safety thermometers, ThermoWorks has a fully operational calibration laboratory that offers NIST-Traceable certificates. Standards are kept for Infrared and contact thermometry and are regularly sent to primary temperature labs to maintain NIST-Traceability.

Our metrology lab employs calibration baths with stabilities to ±0.005°C for accurate probe calibrations. Our Fluke/Hart Scientific metrology standard has a published accuracy to ± 0.000015°C. While we know that you'll never need that type of precision in food measurements, it's nice to know that your performance is backed by high-end standards.

In our infrared calibration lab, we use six different Blackbody Targets from internationally recognized metrology suppliers, and our Humidity Generator has an uncertainty of only 0.5%RH.

Ask your current supplier for a NIST-Traceable certificate and you'll see why so many are switching to the experts at ThermoWorks.


Calibrations are available at pre-determined fixed points or at custom targets defined by the customer. Calibration certificates are offered with new purchases or with recalibration services on units sold by ThermoWorks or by any manufacturer.

Actual test data for each requested target is reported on each certificate showing the individual instrument's recorded error and how it compares with the manufacturer's specification.

NIST-Traceable certificates are available in the following categories and ranges:

NIST-Traceable Probe & Meter Calibrations
Probe calibrations from -112 to 2192°F (-80 to 1200°C)
Meter calibrations from -256 to 2300°F (-160 to 1260°C)
System calibrations offered (i.e. probe and meter together)
Data logger calibrations available (both probe and ambient sensors)
