1.2mm or 3.2mm or 4.0mm J type Thermocouple Bare Wire for Mineral Insulated 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
