Olfasense Group products

The TO8 evolution olfactometer combines the latest scientific and technological advances with decades of practical experience – enabling us to set new benchmarks in the field of olfactometry.

The TO9 evolution olfactometer has all the functionality of the TO8 evolution olfactometer, plus the dual-forced choice method.

The PureSniff system allows the standardised presentation of undiluted odour samples. With a PureSniff device, you can measure an odour’s intensity, hedonic tone and pleasantness by the direct evaluation of an undiluted odour sample.

The main benefit of the PureSniff system is that it allows the standardised presentation of undiluted odour samples.  With a PureSniff device, you can measure an odour’s intensity, hedonic tone and pleasantness by the direct evaluation of an undiluted sample. As the operator triggers a volume flow, the odour sample streams out of the sample bag and passes through a funnel (diffuser) to the human nose. Each olfactory tester or examiner gets an identical odour sample with a standardised volume flow and constant presentation time.

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.

Our standard sampling device is available in two different sizes: The classic version is designed for 10-litre gas sampling bags; the XL version even for 60-litre bags.

The CSD30 is a sampling device for collecting odour samples in gas sampling bags, with a default odour sampling duration of 30 minutes.

The EPD is an easy to use pre-dilution system for highly concentrated odour samples. It has been developed to increase the measuring range at high odorant concentrations for olfactometers.

The GSP can supplement the CSD30 odour sampling device, and dilutes the sample directly at the sampling point. Sample pre-dilution can be performed with nitrogen or synthetic air, whereby the pre-dilution ratio is fixed by the manufacturer (standard 1:10 with individual calibration data). The pre-dilution ratio can, however, be set to different exhaust air conditions on request by substituting the 1:10 screen with a sapphire screen accessible from the outside (e.g. dilution 1:5 or 1:20).
