Product Description

Thermocouple Wire Type J Fiberglass Insulated SS304 Sheath -50→400°C Cable Class I

 

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.
