The AlcoSense Pro is one of the most advanced breathalysers, which takes accuracy, features and ease of use to a new level.

Professional Accuracy

Using a 121mm professional fuel cell sensor, the Pro provides unrivalled accuracy using an advanced sampling system to ensure that only deep lung air is measured. Using sensors to measure blow pressure, flow rate and volume of breath exhaled, the Pro will only take a reading when it senses 1 litre of air has been exhaled, to ensure the most accurate and consistent breath sample is taken. The sensors allow the Pro to advise you how you're blowing in real time, using the AlcoSense patent pending BlowCoachTM technology. Just keep the top-pressure bar in the middle and keep blowing until the bottom volume bar is full. 

Use World-Wide

The AlcoSense Pro can be used anywhere in the World. Just select the country or region you're driving in from the menu and the Pro will set up the device according to local legislation, setting the limit, unit of measure and blood breath conversion ratio to allow accurate readings wherever you are.

Easy to Understand Results

Featuring a 1.8 inch colour TFT screen, the AlcoSense Pro provides clear and detailed readings of your alcohol level. If you're OK to drive, the screen will present in either Green (zero or trace alcohol) or amber (Alcohol present, but under the limit). If you're advised not to drive, the screen will appear Red. 

Store your last 128 readings in memory for easy review at a later stage and be advised when you need calibration and when the outside temperature is outside of the Excel's operating limits, preventing you from obtaining erroneous results. 

The Time Until Sober & Retest Alarm in the AlcoSense Pro will even calclate how long it may take until you'll be sober and show it with your results. 

Comes with AlcoSense Mouthpiece (Pack of 25) & Carry Case

Designed to comply with EN16280 and NF standards, the Mouthpieces are individually sealed an feature a one-way valve for hygiene and accuracy.
