JPX/JNX Type J Thermocouple Cable Multi Strands 24 AWG PVC
insulated And Sheath
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.
