National Temperature Standard in the Range of 962°C to 2200°C

Temperature Scale Realization from 962°C to 2200°C

The temperature scale in the range of 962°C to 2200°C is realized in accordance with the ITS-90 document.

Within this range, the temperature scale is derived from Planck’s law, technically implemented using a blackbody model at the freezing point of gold, and extrapolated using a spectroradiometric pyrometer (Fig. 1, schematic representation in Fig. 2) at a wavelength of 650 nm.

For temperatures below 800°C, the temperature scale is realized using blackbody models, where the temperature is measured by contact thermometers, and the emissivity is determined through calculation and verified by radiometric measurements around the discontinuity points of cylindrical cavities.
