Type K 2x0.81mm Thermocouple Extension Wire Cable
Type K( CHROMEL vs ALUMEL) is used in oxidizing, insert or dry
reducing atmospheres.Exposure to Vacuum limited to short time
periods. Must be protected from sulfurous and marginally oxidizing
atmospheres.Reliable and accurate at high temperatures.
1. Style:Extension Wire
2. Thermocouple extension wire
Thermocouple wire Classification
1. Thermocouple level (high temperature level). This type of
thermocouple wire is mainly suitable for thermocouple type K, J, E,
T, N and L and other high temperature detection instrument,
temperature sensor, etc.
2. Compensating wire level (low temperature level). This type of
thermocouple wire is mainly suitable for compensating cable and
extension wire of various thermocouples of type S, R, B, K, E, J,
T, N and L, heating cable, control cable and so on.
