Rapid Screening

Non contact alcohol screening to detect the presence of alcohol on breath.

For quick use and turnaround, ideal for screening larger numbers at entry points to safety critical sites, the lion AlcoBlow® will detect the presence of alcohol on the breath by blowing on it. If alcohol is detected, you can then investigate further and take a measurement with our screening instruments.

Rapid Test

The lion AlcoBlow® is a simple to use, rapid response instrument used to determine whether or not a person has any alcohol in their breath. It uses the Lion fuel cell sensor, so the reading is unlikely to be affected by anything but alcohol.

There is no physical contact between the subject and instrument, so there is no mouthpiece to replace for each test.

In Active mode the subject blows into the sampling cone until a sample is taken by the instrument for alcohol analysis. Within seconds a coloured LED accompanied by an audible tone indicates whether the sample contains alcohol.  The system then clears itself and within seconds is ready for the next subject test.

In Passive mode the operator draws in a sample of breath from the subject, ideally while they are speaking.  The display then indicates whether or not that subject has alcohol in their body.  The Passive mode is also ideally suited to checking the air above fluids, to see if these contain alcohol.

AlcoBlow® is ideally suited for use in situations where a large number of people have to be tested, and with the minimum of intrusion: for example, Police roadblocks, prisons, at the entrance to a mine, factory or safety-critical establishment.

The instrument should be checked with an alcohol standard at regular intervals, and recalibrated if required.  The user may do this using an AlcoCal® product; or, alternatively, contact Lion to arrange for a calibration at the Lion Laboratories Ltd facility or contact your country distributor for local support.
