Title: Apparatus for measuring concentration of smell
Inventor: HAYASHI YOSHIKAZU
IPC: G01N27/00
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To measure a concentration of smell objectively and easily. SOLUTION: A smell concentration-measuring apparatus 1 is equipped with an injector having a cylinder 3 and a piston 5. An inner wall 3a of the cylinder 3 is fixed to a smell sensor 11. The smell sensor 11 measures a smell of the air in the cylinder 3 and outputs a voltage V corresponding to an intensity of the smell. A control box 7 set in the outer circumference of the cylinder 3 has an electronic control circuit. When the voltage V becomes a value corresponding to an intensity of the smell that cannot be sensed by people, the control box turns on a blue LED 9b in place of a red LED 9r. The sample air is diluted by reciprocating the piston 5. A concentration of the smell is measured by a dilution ratio when a turn-on state of the LEDs 9r, 9b changes.  Since the smell concentration is measured by the dilution ratio, measurement results matching considerably well to the human sense of smell can be obtained.
