Alumina Ceramic Thermocouple-protection Tube One End Closed

Alumina ceramic thermocouple-protection tubes are considered to have better mechanical strength and better chemical resistance. Alumina ceramic thermocouple-protection tubes also have excellent abrasion resistance. Alumina ceramic thermocouple-protection tubes are considered to be gas tight so they make excellent primary protection tubes. Alumina ceramic thermocouple-protection tubes can be for primary and secondary protection tubes on Noble Metal (Platinum based) thermocouples.
