Abstract: . . .  temperature measurement has not received attention from the scientific centers working in this field. There are quite a few models of errors of temperature measurements with thermal cameras. 8 However, the author of this paper is not aware about any scientific papers offering methods of uncertainty evaluation for users of thermal cameras. Therefore the team of the author cooperating with Temperature Radiation Section of Physikalisch-Technische Bundesanstalt, Berlin, Germany has recently published two papers that try to help users of thermal cameras to determine both the intrinsic uncertainty and . . .

The accuracy of determination of these pa- rameters by the user can vary significantly depending on the user and applications. However, it seems that for a case of an experienced user of thermal cameras and in typical application it is always possible to determine the combined stan- dard uncertainty of the output temperature with errors smaller than 20-50%. Such a level of possible error of determination Page 15 of the uncertainty is typically acceptable in many of the industrial plants . . .

This parameter is a measure of accuracy of the thermal camera at real measurement conditions and should be evaluated when the thermal camera is used in the ISO quality systems, metrological institutes or at any center that implemented rec- ommendations of the above mentioned metrological organizations. Any of the two types of uncertainties above mentioned cannot be determined on the basis of data provided by manufacturers of thermal cameras. 2.2 Information offered . . .
