Description

Our company serialized the odor measuring equipment that used the metal oxide semiconductor odor sensor elements and be utilized already widely as product name “e-nose”.<br>The correlation characteristic between e-nose and olfactory sense becomes a problem in the case that the odor strength needs to express it with the unit such as the equivalent value of the odor index or density in olfactory sense measurement.<br>By making the calibration curve that shows the correlation between the odor strength of the measured value of e-nose and the equivalent value of the olfactory sense unit for every measuring compound odor, the problem is solved.
