<P>PROBLEM TO BE SOLVED: To reduce variations in a photographing environment, when measuring gas concentration by a colorimetric method. Ž<P>SOLUTION: Detector paper 12, an illumination device 13, and a photographic device 14 are arranged, inside a case in which the infiltration of external light is reduced. As a result, since a constant photographic environment can be maintained, it is possible to remove errors in ozone concentration measurement due to the differences in the photographic environment, when the amount of ozone exposure is computed through the use of data on photographed images. A temperature and humidity measuring device 15 measures the temperature and the humidity in an ozone concentration measuring device 10, and an ozone concentration computing device 16 corrects the amount of ozone exposure computed through the temperature and the humidity. As a result, it is thereby possible to acquire the more accurate amount of ozone exposure. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
