◆ Non-metalic protection tube thermocouple ◆
● Model : R700 : R701-R702
● 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.
- Furnaces, kilns and ovens
- Furnaces with oxidizing and neutral atmosphere
- Glass, fiber and ceramic industries
