Product Details
noble metal thermocouple
OverviewPrecious metal platinum rhodium thermocouples use high-purity platinum as the negative electrode and platinum rhodium alloy as the positive electrode. They are used in powder metallurgy, sintering bright furnaces, vacuum furnaces, smelting furnaces, and various refractory materials, ceramics, and porcelain firing. The outer tube material is corundum tube, and the measurement temperature is 0-1800 ℃.
