Thermocouple Cable Type J Fe CuNi45 Wire with High Tensile Strength and Volume Resistivity for Temperature Monitoring

Type J (Fe CuNi45) Thermocouple Wire 0.193mm Diameter Compliant for High-Temperature Sensing 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 1.
