ABSTRACT OF THE DISCLOSURE A remote-reading IR thermometer is provided by means of which the temperature of an object can be measured in a non- contacting manner from a given distance, using a line detector on a screen scanning at a rate of approximately 25 Hz. The thermometer includes an image-processing electronic system for providing an IR image, such image being homogenized by detector elements which change from image to image to build up each line on the screen. The thermometer also includes a blackbody radiator of known and regulated temperature. Means are provided for the input of atmospheric correction factors into the image-processing electronic system. The temperature of the object is determined by comparing the radiation output of the object with the output of the blackbody radiator. A temperature-regulated reference surface is preferably used as the blackbody radiator in the thermometer and all the signals emanating from the object are related to the signal from this surface. Since atmospheric correction factors are input into the image-processing electronics, the atmospheric damping of the radiation output of the object is directly allowed for.
