Platinum and rhodium 13 platinum (R-type thermocouple) is a noble metal thermocouples. Thermocouple wire diameter is defined as 0.5mm, tolerance -0.015mm, its positive (RP) is the name of the chemical composition of platinum and rhodium alloy, which contains 13% rhodium, platinum 87%, negative (RN) of pure platinum, platinum rhodium thermocouple 30 sales price, long-term maximum use temperature of 1300 ℃, short-term maximum temperature of 1600 ℃. WRQ-R platinum-rhodium thermocouple thermocouple series has the most accurate, best stability, temperature of wide-temperature, long life and other advantages. Its physical and chemical properties of good, thermoelectric power at high temperature stability and good oxidation resistance, suitable for oxidizing and inert atmosphere. Since R-type thermocouple overall performance with S-type thermocouple equivalent price of platinum and rhodium thermocouple 30, it has been difficult to promote in our country, in addition to temperature measurement on some imported equipment applications, platinum and rhodium thermocouple 30, domestic temperature rarely used. From 1967 to 1971, the British NPL, NRC Canada, the United States NBS and three research institutions conducted a joint research, the results show that the stability and reproducibility R-type thermocouples are better than the S-type thermocouples, our current Not to carry out research in this area. 30 platinum and rhodium thermocouple manufacturers, Anhui Global, platinum and rhodium thermocouple 30 provided by the Anhui Global instrument cable Limited.
