Industrial Thermometer Calibration Laboratory

The Industrial Thermometer Calibration Laboratory calibrates liquid-in-glass thermometers, industrial platinum resistance thermometers, thermistors, and thermocouples in the temperature range -196 ºC to 550 ºC. Calibrations in this laboratory are made by comparison with a calibrated standard platinum resistance thermometer in stirred liquid baths. Fixed-point measurements at the Ga melting point (29.7646 °C) [for a thermometer with an outer diameter of less than 3.6 mm], the water triple point (0.01 °C) and the ice point (0 °C) are available.

Thermometer Temperature Range
IPRT's -196 °C to 550 °C
Thermistors -196 °C to 100 °C
Thermocouples -196 °C to 550 °C
Liquid in glass -196°C to 400°C
Digital -196 °C to 550 °C
