What is a thermocouple and how does it work?

A thermocouple is a sensor for measuring temperature. This sensor consists of two dissimilar metal wires, joined at one end, and connected to a thermocouple thermometer or other thermocouple-capable device at the other end. When properly configured, thermocouples can provide temperature measurements over wide range of temperatures.

How to select thermocouple equipment - Fluke Cal

Thermocouple calibration equipment. Calibration is performed by measuring the voltage output of the thermocouple unit under test (UUT) while the measuring (hot) junction is exposed to a temperature source and the reference (cold) junction is maintained at a reference (usually 0 °C). The following instruments are required: Reference probe.
