BS Lion AlcoBlow Breathalyzer
The Lion AlcoBlow Breathalyzer is a simple to use, rapid response instrument that is used simply to determine whether or not a person has any alcohol in their breath at all. It uses the Lion fuel cell sensor, so the reading is very unlikely to be affected by anything but alcohol in the subject's breath. It is not an evidential device, for this you should look towards the Lion 500 or Lion SD400.
In Active mode the subject blows into the sampling cone until a sample is taken by the instrument for alcohol analysis – fully automatically. Within seconds a coloured light appears, with a beep tone, to indicate whether that sample contained alcohol.
In Passive mode the operator presses the Passive button to draw in a sample of breath from around the subject, ideally while they are speaking. Display system then very quickly shows whether or not that subject has alcohol in their body. This Passive mode is also ideally suited to checking the air above fluids, to see if these contain alcohol.
