Classification of Thermocouple Bare Wire
Thermocouple level (high temperature level). This type of thermocouple wire is mainly suitable for thermocouple of type K, J, E, T, N and L and other high temperature measuring instruments, temperature sensors, etc.
Compensating wire level (low temperature level). This type of thermocouple wire is mainly suitable for compensating cable and extension wire of various thermocouples (like type S, R, B, K, E, J, T, N and L), heating cable, control cable, and so on.
