Introduction
Zirconia thermocouple protection tubes are made from fully stabilised yttria zirconia. Tech Ceramic zirconia thermocouple protection tubes offer corrosion and chemical resistance at higher temperatures. The zirconia tube does not react with the inert gas, thereby avoiding the contact between the ceramic tube and the gas, and effectively improving the service life of the thermocouple.
