Type T Thermocouple Extension Wire Essential For Temperature Control In Laboratories And Industrial Processes

Cu-CuNi, Type T thermocouple extension wire, is recognized for its accuracy and stability in temperature measurement, particularly in low to moderate temperature ranges. Composed of a copper (Cu) positive leg and a copper-nickel (CuNi) negative leg, Type T thermocouples are designed for temperatures between -200°C and 350°C. They offer high sensitivity, approximately 43 µV/°C, and are known for their repeatability and resistance to oxidation in moist conditions. Type T thermocouples are widely used in cryogenic applications, laboratory settings, food processing for temperature control during cooking or freezing, and various industrial processes where precise temperature monitoring is essential. Their versatility and compatibility with standard measurement equipment make them a popular choice for applications requiring reliable temperature data in moderate temperature environments.
