Thermocouple grade wire is wire that is used to make the sensing point (or probe part) of the thermocouple. Extension grade wire is only used to extend a thermocouple signal from a probe back to the instrument reading the signal. The extension grade wire typically will have a lower ambient temperature limit in which the wire may be used.

Concept of Thermocouples. A thermocouple is composed of two dissimilar metal and/or semiconductor wires joined together. To use a thermocouple, we place the junction in the test environment and keep the two ends outside test environment at a reference temperature. Figure (PageIndex{3}) demonstrates the proper setup for using a thermocouple.
