Industrial Thermometer Calibrations
The Industrial Thermometer Calibration Laboratory calibrates the following:
- Industrial thermometer probes
- platinum resistance (IPRT)
- thermistor
- thermocouple
- Digital readouts with attached probes
Calibrations in this laboratory are made by comparison with an ITS-90 calibrated standard platinum resistance thermometer in stirred liquid baths in the temperature range –196 ºC to 550 ºC.
Fixed-point measurements at the water triple point (0.01 °C) and the ice point (0 °C) are available.
How to Arrange a Calibration
- Go to Shop NIST web page
- Down arrow for Calibrations
- Scroll to Thermodynamic and click
- Scroll to Laboratory and Industrial-Grade Thermometers and click
- Please note that NIST no longer calibrates Liquid in Glass thermometers
- Click the appropriate service description and follow the instructions on that page
- If you have questions send email to wmiller [at] nist.gov (wmiller[at]nist[dot]gov) or itcl [at] nist.gov (itcl[at]nist[dot]gov).
