An olfactometer is an instrument used to detect and measure odor dilution. Olfactometers are used in conjunction with human subjects in laboratory settings, most often in market research, to quantify and qualify human olfaction. Olfactometers are used to gauge the odor detection threshold of substances.

What is the meaning of Olfactometry?

Medical Definition of olfactometry

: the testing and measurement of the sensitivity of the sense of smell.

Can you quantify smell?

Odors are normally quantified by dynamic dilution olfactometric analysis. Olfactometric analysis consists of determining the olfactory perception threshold of a gaseous sample. The olfactory perception threshold is defined as the number of dilutions at which 50% of a jury perceives the odor while 50% do not.
