Document Type and Number:
WIPO Patent Application WO/2023/042559
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide an odor measuring device, an intake type odor measuring device, and an odor measuring method suitable for measuring low-concentration odors. [Solution] An odor measuring device according to the present invention includes a sensor chamber, a processing chamber, a first flow path, a second flow path, a supply section, and a measurement unit. The sensor chamber accommodates a sensor that detects odorants, and has a first inlet and a first outlet. The processing chamber accommodates the object to be measured and has a second inlet and a second outlet. The first flow path connects the first outlet and the second inlet. The second flow path connects the second outlet and the first inlet. The supply section circulates a gas between the sensor chamber and the processing chamber via the first flow path and the second flow path. The measurement unit acquires the detected value from the sensor and measures the odor based on the detected value.
