JPX/JNX Type J Thermocouple Cable Multi Strands 24AWG
JPX/JNX Type J Thermocouple Cable Multi Strands 24AWG
TYPE J (Iron vs Constantan) is used in vacuum, oxidizing, inert or reducing atmospheres. Iron element oxidizes rapidly at temperatures exceeding 538°C, and therefore heavier gauge wire is recommended for longer life at these temperatures.
