1.3mmx2 AWG 16 Type K Thermocouple extension Cable fiberglass Insulation
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.

Type K Extension Cable Chromel / Alumel Material FEP insulation
Type K (CHROMEL vs ALUMEL ) is used in oxidizing, inert 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.
