Product Description

Gas Thermocouple Cable Stainless Steel Sheath Multistrand Type J Thermocouple Cable

 

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.
