摘要：

It has been found that noble metal thermocouples can yield a thermoelectric temperature scale accurate within +/- 0,1-degrees-C from ambient to at least the silver point (962-degrees-C) if they are calibrated after they have been heat treated into a reasonably stable thermoelectric state. However, the calibration is only valid for the particular section of the thermocouple wire that was calibrated. The use of any other, uncalibrated, sections of the thermocouple wire would render accurate calibration irrelevant.
