High Temperature Unprotected Thermocouple
Brand: SOR IncMullite and Alumina Tubes are 98% pure alumina oxide and can be used with all thermocouple calibrations including noble metals.
Good general-purpose use. Use for all atmospheres with temperature rating of 1,871° C (3,400° F).
Has fair resistance to thermal shock. Mullite is preferred for oxidizing atmospheres and can not be used with noble metal thermocouples.
Maximum temperature rating is 1,649° C (3,000° F). Both Mullite and Alumina should be heated prior to process insertion.
Hexoloy Tubes Excellent abrasion resistance and high resistance to thermal shock, also has good thermal conductivity (3 times greater than stainless steel).
Due to its toughness it can be used in high pressure and velocity environments. Maximum temperature rating is 1,593° C (2,900° F).
