QUANTITATIVE MEASUREMENT SYSTEM FOR OIL POLLUTED SOIL

PROBLEM TO BE SOLVED: To improve accuracy in quantitatively measuring oil odor with an odor sensor.SOLUTION: An odor quantitative measurement system which is portable includes: a specimen container 2 which has a first vent hole 8 for supplied air and a second vent hole 9 for recirculated air, and is sealed except for the two vent holes; an odor sensor 14 which has an air intake 16 and an air exit 18 and is configured to take in an air containing an odorous component from the air intake and discharge the air from the air exit after measuring intensity of an odor; and communication pipes 12A, 12B connecting the first vent hole of the specimen container to the air intake of the odor sensor, and the air exit of the odor sensor to the second vent hole of the specimen container. The system configures a circulation type air circulation path C which passes through the communication pipes, and the insides of the specimen container and the odor sensor.
