Features/Usage:

Thermocouple compensating wires are a pair of insulated wires with the same nominal value as the thermoelectric electromotive force of the matched thermocouple within a certain temperature range (including room temperature). They are used to connect the thermocouple and the measuring device to compensate for the errors caused by temperature changes at their connection with the thermocouple. It is divided into two types: extension type and compensation type.
