Product Description

Fe/CuNi Type J Thermocouple Alloy Bare Wire

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.
