摘要：
The radiation temperature scale for a pyroelectric detector based thermal infrared thermometer with its spectral response from 8 mu m to 14 mu m was realized in the temperature range from 0 degrees C to 232 degrees C by using four fixed-point blackbodies (ice, Ga, In and Sn). The Planck version of the Sakuma-Hattori equation was used to interpolate the scale between the fixed-point temperatures that are corrected by considering a size-of-source effect (SSE). The expanded uncertainties (k = 2) of the scale were estimated to be 108 mK for ice, 99 mK for Ga, 175 mK for In and 234 mK for Sn.
