GAS-DETECTING TUBE PHOTOGRAPHIC DEVICE, GAS-DETECTING TUBE MEASURING APPARATUS, AND GAS CONCENTRATION MEASURING SYSTEM AND METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a gas-detecting tube photographic device capable of obtaining stable images, when simultaneously photographing a plurality of gas-detecting tubes using a camera. SOLUTION: The gas-detecting tube photographic device comprises a support member 106 for arranging the plurality of gas-detecting tubes 100 in the same plane; a planar emission-type illuminating means 103 for illuminating the plurality of gas-detecting tubes 100 supported by the support member 106; and a chassis 101 for blocking external light from entering the space between the illuminating means 103 and the camera 110 for photographing transmitted light that is a portion of illuminating light from the illuminating means 103 which passes through the plurality of gas-detecting tubes 100.
