thermocouple platinum rhodium thermocouple

Platinum rhodium thermocouple is made of noble metal,( platium in high purity as cathode,Platium and Rhodium alloy as positive pole), corundum as external tube, which is used to measure as high as 1800C like powder metallurgy,fritting furnace,vacuum furnace, matallurgy furnace and calcination of fire-proof materials, proclein, ceramics. 


It is widely used in high temperature production process such as glass, ceramic industry and industrial NaCl bathing stove, etc. 


Advantages: 1.easy assembly

     2. convenient for replacement

    3.  high mechanical strenghth

    4.good pressure-resistant

    5.good shock-proof permance;
