Abstract

Blackbody models are used as referential temperature measuring gauges for radiationthermometers calibration. Their emissivity is usually determined by calculation. Thepresented paper describes an experimental device used to measure local effectiveemissivities, using an optical radiometer. The methods to measure and evaluate emissivityand temperature are described. The results are compared with the theoretical model of acylindrical-conical cavity used to calibrate radiation thermometers.
