Abstract:
An odor measuring apparatus, comprising:a plurality of detecting means having different characteristics and adapted to contact a sample gas for detecting odor components in the sample gas and providing detection outputs and a pattern of the odor components contained in the sample gas, odor fractionating means electrically connected to the detecting means and having a memory memorizing patterns of the odor components for typical odor categories in advance, said odor fractionating means determining that odor in the sample gas belongs to one of the odor categories memorized in the odor fractionating means based on the pattern of the odor components obtained from the detecting means, and computing means electrically connected to the detecting means and the odor fractionating means and having a memory memorizing regression lines determined in advance for the odor categories, said computing means calculating an index value regarding the odor in the sample gas based on the detection outputs obtained from the detecting means by using one of the regression lines determined in advance for the odor categories.
