Our Industrial Base Metal Thermocouples offer a wide variety of ceramic insulated thermocouples in a large selection of wire sizes. All standard thermocouples (types E, J, K & T) come with a standard length of 12 inch leads. Noble metal and refractory wire elements (types B, C, D, R & S) come with a standard element length of six inches. Other sizes and/or lengths are available upon request.

Mullite ceramic insulators are recommended for use with base metal thermocouple wire and elements types E, J, K, N & T. High purity Alumina oxide is recommended for use with noble or refractory thermocouple wire and elements, types B, C, D, R & S. Alumina is suitable for up to 3,600 degrees Fahrenheit. Mullite (60% AL2O3 / 39% SiO2) is suitable to 2,700 degrees Fahrenheit.
