Type T thermocouple wire

Type T bare thermocouple wire is a Cu-CuNi thermocouple wire particularly suited to low-temperature and cryogenic temperature measurement. The stated temperature range is -270°C to +370°C. Type T can be used in oxidising, reducing and inert atmospheres and is also suitable for moist environments. Kamet supplies Type T wire in IEC 60584 Class 1 for applications including ultra-low freezers, laboratories and food processing.

Which environments are suitable for Type T thermocouple wire?

The type T thermocouple is versatile, functioning well in both oxidising and reducing atmospheres, though a protecting tube is advised for extended life.

It is particularly stable at low temperatures, making it an excellent choice for a wide range of applications in low and cryogenic temperatures, with an operating range of -200°C to 370°C, and capability down to -269°C.

Widely used in the food industry due to its high accuracy and good performance in moist environments without oxidising.

The type T thermocouple wire can also be used in MI thermocouple cable. More about MI cable with type T thermocouple.

Why is Type T thermocouple wire suitable for cryogenic temperatures?

Type T thermocouple wire is particularly stable at low temperatures and is used for cryogenic and other low-temperature measurement applications. The stated applications include ultra-low freezers and laboratory environments.
