Product Desciption
Type-J Iron -Copper nickel /constantanThermocouple alloy resistance wire high temperature 100 degree to760 degrees for thermocouple sensor/electrical cable
Type J Thermocouple is frequently used for its low cost and high EMF It can be used in oxidizing conditions up to 760°C. For higher temperatures, it is recommended to use large wire diameters.
Type J thermocouple is suitable for oxidizing, reducing inert atmosphere or vacuum.
