Corrosion Resistant Thermocouple Tube is suitable for temperature measurement in applications such as steel melting and industrial heating furnaces having operating conditions up to 1800 ° C. The Tube ensures protection to the measuring sensors from a corrosive atmosphere and simultaneously protects the thermocouple sensors against mechanical damage. The Corrosion Resistant Thermocouple Tube is thermal shock resistant, high temperature resistant, corrosion resistant and has high thermal conductivity.
