PureSniff - Model III -Direct Evaluation Device of Odour Sample
The PureSniff III consists of three sealed tubes, which are set up with gas sample bags independent of each other, allowing for individual or direct evaluation comparison tests. For example, each tube can be set up as three separate samples for evaluation or duplicate/triplicate of the same sample. Alternatively, discriminations tests of 2-3 samples can also be run. Examples include triangle tests, 3-AFC, or A – not A.
The operator triggers a volume flow by activating a push-button. The odour sample is pushed out of the gas sample bag and press through a funnel (diffuser) mask to the human nose. Each olfactory assessors gets an identical odour sample with standardized volume flow and constant presentation time. As a default setting, the samples is presented for 2.5 seconds at a volume of 20-LPM.
Using a 10-L gas sample bag filled to approximately 70%, one sample serves for about 10 presentations.
