Ceramic E-Mitters are manufactured in a casting process embedding the resistance wire in the ceramic material. Standard colors are metamorphing rose (cold) to grey (hot), and traditional white. Optional colors are metamorphing yellow (cold) to orange (hot), and black. Units are available with a built-in type K thermocouple (optional Type J). Low electrical noise thermocouple options are also available. Ceramic E-Mitters can be supplied with individual reflectors or mounted in custom structural arrays.
