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, R-type platinum-rhodium thermocouple principle, suitable for oxidizing and inert atmosphere. Since R-type thermocouple overall performance with S-type thermocouple fairly, in our country has been difficult to promote, in addition to temperature measurement on some imported equipment applications, internal temperature rarely used. From 1967 to 1971, the British NPL, R-type platinum-rhodium thermocouple parameters, United States and Canada NRC NBS three research institutions conducted a joint research, the results show that the stability and reproducibility than the R-type thermocouple S type thermocouple are good, China has yet to carry out research in this area. After following instrument wiring diagram for proper wiring powered thermocouple meter display instrument first indexing number, R-type platinum-rhodium thermocouple, then display the span of the instrument, and then the next row of measuring instruments digital display on the set temperature, the meter row digital display measuring temperature. Thermocouple can not be installed in a small area of ??the measured medium flows, R-type platinum-rhodium thermocouple how to sell, when used in the thermocouple measuring gas temperature, it is necessary to install the thermocouple against the direction of flow, and full contact with the gas .
