Original Abstract

Many testing methods determining thermal emissivity of various materials have been published so far but the methods estimating the virtual emissivity of infrared thermometers themselves are not commonly available and users have to rely on manufacture information. However, not all manufactures provide the value of virtual emissivity along with their infrared thermometers and users who need this value for their special laboratory work are forced to find a method for estimating this quantity. In this paper, a method for the estimation of virtual emissivity of infrared thermometers is described. It is based on comparative method that uses two precise black body etalons of different emissivities and heated to the same temperatures. The infrared thermometer measures repeatedly the temperature of each etalon and the statistical ensemble of measured values is processed by the graphical-numerical procedure. The statistical uncertainty of this procedure is analyzed and showed that results are of acceptable accuracy if the used devices ensure sufficiently high precision.
