PURPOSE:To measure the temperature distribution in a space speedily without any error by arranging plural detection plates made of materials with small heat capacity in the space where the temperature distribution is to be measured, and measuring the temperatures of the detection plates by an infrared radiation thermometer. CONSTITUTION:The detection plates 3 are arranged in a lattice shape so as to measure the temperature distribution in the internal space surrounded with building external walls 1 and a building roof 2. Connecting lines 4 connect the detection plates 3 longitudinally and laterally and they are suspended by a wire rope 5 passed around a pulley 6 supported by a metallic fixture 7 to measure the temperatures of the individual detection plates 3 by the infrared radiation thermometer 8, thereby measuring the temperature distribution. The detection plates 3 are made of materials with small heat capacity, e.g. thin copper plates and the size is determined according to the resolving ability of the thermometer 8. When the size and arrangement of the detection plates 3 are determined, they are installed no so closely so that no influence is exerted upon the air flow, temperature distribution, etc., at the measurement position. The detection plates 3 clamps the connecting wires 4 by pressers 9 and are slid to shift in position.
