Thermocouple, type K for American kilns

Dimensions: 150 mm long with 100 mm long ceramic insulator tube, approximately 12 mm diameter. The negative connection is marked red. The space between the two wires is smaller than the space between the two holes in the thermocouple protection block and it will take some work to install these in the block. They need to be bent and straightened out to fit in the holes. Be sure you are comfortable doing this if you purchase just the element and not the entire thermocouple assembly.
