Abstract：The calibration method of 0.9 μm pyrometer with variable-temperature blackbody as reference source is introduced. The uncertainty source of the pyrometer is analyzed through the measurement of the gain ratio, the size-of-source effect and the distance effect. Moreover, the other vital factors such as stability and uniformity of high-temperature blackbody are analyzed. The new method extended the wavelength range of the existing pyrometer. The expanded uncertainties of the scale are 0.6～1.2 ℃ （k=2） between the temperature range 600～2 000 ℃.
