Description

KP/KN Thermocouple Extension Wire 1.0mm AWG 18 Diamter

Specifications:

1.Style:Extension Wire
2.Thermocouple copper 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.
