PURPOSE:To obtain a thermometer having a high response speed and enabling the measurement of a distribution of thermal radiation, by a method wherein a plurality of thin heat flow meters are fitted on the outer surface of the thermometer so that they are distributed thereon uniformly, and an output of the thermometer is corrected by outputs of the heat flow meters. CONSTITUTION:Heat flow meters 3 five in numbers, for instance, are stuck almost uniformly on the outer surface of a globe 1. The heat flow meters 3 are shaped in flat thin plates and deliver heat flow outputs H1-H5 respectively, sensing radiation from the face-to-face direction. Outputs of an inner-globe thermometer 2 and each heat flow meter 3 are inputted to a data logger 4, and the readings of these meters are computed by a computer 5 in such a manner that the reading of the inner-globe thermometer 2 is corrected by that of the heat flow meter 3. In other words, the correction is made with regard to each heat flow meter 3 by using a relationship formula, and the temperature Tgc of a globe thermometer after the correction is shown on a display 6, so that a heat radiation distribution around the globe thermometer can be known. In addition, an anemometer 7 and an air temperature meter 8 are provided, and by using outputs (v) and Ta and Tgc, MRT (Mean Radiant Temperature) can be calculated from a relationship formula.
