Пожалуйста, помогите перевести.

Слово встречается в следующем контексте:
the TECNODOR is a patented suprathreshold dynamic dilution olfactometer which uses a referencing substance. It provides sensory measures of unpleasant odours. The sensory measure calls on humans (the jury) to compare the intensity of an unpleasant odour with that of a neutral reference odour of known concentration in the air. As a function of this reference odour, 1-butanol, the TECNODOR allows the intensity of an odour to be quantified and its profile determined. These data can also be used to determine the persistence and threshold of an odour.
