The influence of the distance of the pyrometer from the surface of the radiating object on the accuracy of measurements

During the COVID-19 epidemic, non-contact body temperature measurement has become very important. This dataset contain results of measurements of the four professional commercially available pyrometers. The CHY 314P, TM-F03B, TFA 31.1125 and Abatronic AB-8855 where tested in function of measuring distance from the surface of the radiating black body. Set temperature of the black body was 81 °C to allow easy catch when the measurement starts to be incorrect. The dataset contains also results of calculated pyrometer view area in function of measuring distance.
