  • Thermocouples at The Ceramic Shop - The Ceramic

    Type-K thermocouples function over a temperature range of -300F to 2450F, so they fit the needs of the majority of ceramicists. A Type-K thermocouple is made up of two dissimilar metals: alumel and chromel. Where the two metals meet, they are welded together to form the tip of the thermocouple, which is where the heat in your kiln is sensed.
