Cu-CuNi Type T Constantan Thermocouple Wire For Low Temperature Measurement with High Temperature Stability

Cu-CuNi (Type T) Constantan Thermocouple Wire For Low Temperature Measurement

Cu-CuNi (Type T) Constantan Thermocouple Wire, also known as Type T thermocouple wire, is composed of a copper (Cu) positive leg and a copper-nickel (CuNi) negative leg. Type T thermocouples are particularly suited for low-temperature applications, as they offer accurate readings within a temperature range of -200°C to 370°C. Due to its high stability and resistance to oxidation in moist environments, this thermocouple wire is widely used in applications requiring reliable and precise measurements at sub-zero temperatures.

The high accuracy and stability of Type T make it a preferred choice for cryogenic applications, scientific research, and cold storage monitoring. Additionally, it is often employed in food processing, pharmaceuticals, and other industries that require accurate temperature control in cold environments.

Type T thermocouples provide excellent linearity over their temperature range and are highly resistant to environmental corrosion, which contributes to their longevity and consistent performance. Overall, Cu-CuNi (Type T) thermocouple wire is valued for its precision, durability, and adaptability, particularly in applications involving low and moderate temperatures where accuracy is essential.
