No. Dividing different measuring temperature, - 200℃- Choose at random (1800 ℃ S type thermocouple) Platinum rhodium - 10 Platinum thermocouple platinum rhodium - 10 Platinum thermocouple ( S type thermocouple) For precious metals thermocouple. Regulation of 0 S type thermocouple pair wire diameter. 5 mm, allowable deviation - 0. The positive (015 mm, SP） In the name of the chemical composition of platinum rhodium, contain the rhodium is 10%, platinum-based is 90%, the cathode ( SN) For pure platinum, commonly known as single platinum-rhodium thermocouple. The temperature is 1300 ℃, the long-term use of thermocouple short-term use temperature is 1600 ℃. S type thermocouple in the thermocouple series has high accuracy, good stability, test your area wide, long service life, etc. Its physical and chemical performance is good, the thermoelectric potential stability and oxidation resistance at high temperature performance is good, suitable for oxidizing and inert atmosphere. Because of S type thermocouple has excellent comprehensive performance, in line with the use of S type thermocouple temperature scale, for a long time as a scale interpolation instruments, 'ITS - Although 90 'provisions will not be as within the scale of the instrument, but temperature advisory committee ( 有条件现金转移支付) That S type thermocouple can still be used for approximate scale. S type thermocouple deficiency is thermoelectric potential, thermoelectric potential rate is small, low sensitivity and mechanical strength under high temperature to drop, is sensitive to pollution, precious metal materials is expensive, and one-time investment is larger.
