Acetone Comparative Scale

The Acetone Comparative Scale by Olfasense is a comparative scale in accordance with ISO 16000-28, as well as ISO 16000-30 and VDI 4302, for the controlled presentation of concentrations of acetone in air for the purpose of a comparative estimation of odour intensity.

The 16 different concentrations (PI scale 0 -15) are created through the dosing and evaporation of liquid acetone into an open jet of the carrier air and presentation to the panel members by means of a glass nose funnel.

The Acetone Comparative Scale satisfies the requirements of ISO 16000-28 , as well as ISO 16000-30 and VDI 4302, and allows the creation of the 16 levels after a free selection of the panel member.

Liquid acetone is required for the operation of the Acetone Comparative Scale. By calibrating the device with a suitable monitor (e.g. FID), the user can set it to the desired PI levels.

The Acetone Comparative Scale consists of a housing with a touch display as a user interface and a nose funnel for presenting the sample to the test person.
