Abstract :
Topcon 0.65 mum and 0.9 mum radiation thermometers are used as the standard thermometers at high temperatures. These radiation thermometers employ three to five ranges to cover their whole temperature ranges. The range ratios of these thermometers influence largely on the calibration uncertainty. The measurement method, measured results and the long term stability of the range ratios are shown.
