The AlcoMate Prestige Breathalyzer is very simple to use - just hold the button until it bleeps, wait a few seconds for the countdown while the unit clears its sensor, then as soon as it bleeps again just blow through the mouthpiece. The unit will indicate when sufficient breath sample is obtained (after about 5 seconds), then the result will appear in the digital display. Results read from zero tolerance all the way up to several times over the legal drink drive limit in the UK. The result is expressed as % blood alcohol concentration or %BAC, so it is suitable for use in any country or jurisdiction. Overall, an ideal portable personal breathalyzer machine.
