Type T bare thermocouple wire

The type T Cu-CuNi thermocouple is known for its stability and is particularly well-suited for cryogenic applications. It has a specified temperature range of -270°C to +370°C, making it ideal for use in extremely low temperatures, such as in cryogenics or ultra-low freezers, as well as various laboratory environments.

This thermocouple can operate effectively in temperatures below 0°C up to an upper limit of 370°C. Its composition allows it to be used in oxidizing, reducing, or inert gas atmospheres, and it does not corrode in moist atmospheres.

Environment and industrial usage

The type T thermocouple is versatile, functioning well in both oxidizing 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 oxidizing.

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