Abstract
A detector detects the color of a medium after a gas to be identified and a reagent have chemically reacted with each other on the medium. A controller identifies color information, which is most similar to the color detected by the detector, from color information stored in a spectral database, and reads gas identifying information related to the identified color information, as gas identifying information representing the gas to be identified, from the spectral database.
