For temperatures above 1100 ° C, Noble Metal thermocouples made from precious or noble metals such as Platinum and Rhodium should be used and must be placed inside a ceramic protective sheath to protect the thermocouple. These sensors are usually fragile and should not be used in applications where the temperature rises or falls sharply. If used, the rate of temperature change should be controlled and the next destructive factor is metal vapors that will corrode the thermocouple wires.

Ceramic pods in two types of C610 or so-called PYTHAGORAS, which have a purity of 60% alumina and can withstand temperatures up to 1500 ° C, and the next type C799 or so-called alsinite (ALSINT 99.7), which has a purity of 99.7% alumina and up to temperature 1600 ° C has a temperature tolerance.
