Technical parameters of standard thermocouples

Technical parameters of thermocouples:

Scale thermocouples are thermocouples in the thermocouple series that are moderately high, have excellent physical and chemical properties, good oxidation resistance at low temperatures, and have good stability and reproducibility of thermoelectric potential. Scale thermocouples are further divided into first-class platinum rhodium 10 platinum thermocouples and second-class platinum rhodium 10 platinum thermocouples.

The first scale platinum rhodium 10 platinum thermocouple is used to calibrate the second scale platinum rhodium 10 platinum thermocouple; Second scale platinum rhodium 10 platinum thermocouples are used to calibrate industrial thermocouples and accurately measure temperatures within the range of 300 ℃ to 1300 ℃.

Second grade Platinum Rhodium 30-Platinum Rhodium 6 is used for calibrating industrial scale Platinum Rhodium 30-Platinum Rhodium 6 thermocouples and for fine measurement. Second grade copper constantan thermocouples are used for verifying industrial thermocouples and for fine measurement.
