Non-metallic
protection tube thermocouple
Model : R700 Series
Service intended
This Thermocouple is the combination of a precious metal such as
Platinum and Rhodium alloy with Non-Metallic materials such as
alumina and ceramic which can withstand a high temperature.
It is mainly used in a furnace, Kilns, and a production line of glass and
ceramic.
