Abstract
An odor discriminating apparatus includes: a measurement chamber including multiple pieces of odor sensors; a gas introducer for introducing a sample gas into the measurement chamber; concentration adjuster for diluting or condensing the sample gas before introducing the sample gas into the measurement chamber; a vector length computation unit for plotting, in a multidimensional space formed by axes corresponding to detection signals generated by each piece of odor sensors, a measurement point representing a measurement result of the sample gas and for computing a vector length of an odor vector directed from an origin of the multidimensional space to the measurement point; and a controller for feedback-controlling the concentration adjuster so that the vector length computed by the vector length computation unit reaches a predetermined target value.
