Type T thermocouple wire, Cu-CuNi

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.

In short:

  • available in diameters ranging from 0.30 mm to 3.50 mm
  • provided in IEC 60584 Class 1
  • supplied with an 3.1 certificate and a calibration certificate
  • produced in EU with EU sourced materials
  • an excellent choice for inert and oxidizing cryogenic environments of -270°C to +370°C
  • often used in the food processing industry, ultra-low freezers and laboratory environments

Environmental and industrial usage

The type T thermocouple is versatile, functioning well in oxidizing, reducing, or inert gas atmospheres. However, it requires protection from contamination to prevent embrittlement, making it a reliable yet delicate tool for precise temperature measurements.

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.
