Type K Extension Cable Chromel / Alumel Material FEP insulation
Specifications
1.Style:Extension Wire
2.Thermocouple copper wire
Thermocouple copper 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.
