Durable Type T Thermocouple Extension Alloy For Accurate Temperature Measurement In Labs And Industrial Environments
Durable Type T Thermocouple Extension Alloy for Accurate Temperature Measurement in Labs and Industrial Environments
Type T thermocouples are widely used for low-temperature measurements due to their stable and accurate performance in such conditions. They consist of a Copper (Cu) positive leg and a Constantan (CuNi) negative leg. The Type T thermocouple extension alloy wire is specifically designed to extend the leads of Type T thermocouples without altering their thermoelectric properties, ensuring accurate temperature readings over a greater distance.
