Abstract

A substance sensor includes sensitive membranes to react with substances included in the odors of a gas in correspondence with the substances, and is configured to detect the reaction values of the sensitive membranes. An odor specifier specifies the odors of the gas on the basis of the reaction values of the sensitive membranes. A reaction value calculator calculates reaction values corresponding to the odors specified by the odor specifier on the basis of the reaction values of the sensitive membranes. A percentage calculator calculates the percentages of the reaction values corresponding to the odors specified by the odor specifier to the total of the reaction values corresponding to the odors. A display displays the percentages of the reaction values corresponding to the odors, calculated by the percentage calculator, so that comparison of the percentages is enabled between the odors specified by the odor specifier.
