Cleveland Electric Laboratories offers individual elements in standard and special limits material, as well as all components or full assemblies.

Type K – Due to its reliability and accuracy, Type K is used extensively at temperatures of up to 2300ºF. It is good practice to always protect this type of thermocouple with a suitable metal or ceramic protection tube, especially in reducing atmospheres. In oxidizing atmospheres and when other conditions are suitable, tube protection is not always necessary; however, protection is recommended for cleanliness and general mechanical protection. Recommended temperature range is 32ºF to 2300ºF.

Type J – This element may be used, protected or unprotected, where there is a deficiency of free oxygen. To maintain cleanliness and generally longer life, a protection tube is recommended. Because Type J wire will oxidize rapidly at temperatures over 1000ºF, it is recommended that larger gauge wire be used to compensate. Recommended temperature range is 32ºF to 1400ºF.

Type T – Useable in oxidizing, reducing or inert atmospheres, as well as vacuum applications. Not subject to corrosion in moist atmospheres. Recommended temperature range is 328ºF to 662ºF, but can be used to -425ºF.

Type E – This thermocouple is suitable for use in temperatures up to 1652ºF in a vacuum, inert, mildly oxidizing or reducing atmosphere. Recommended temperature range is 32ºF to 1600ºF.

Type N – This thermocouple is used primarily at high temperatures of up to 2300ºF.
