 TRIED AND TESTED 

Enjoyed a night on the town with a few shandies and worried that your early morning ride-out might be affected? That’s where these new pocket-sized home breathalysers come in. Designed to be quick and simple to use, the AlcoSense Pro uses a 121mm2 version of the fuel cell sensor used in police kit. Other sensors measure blow pressure, flow rate and breath volume and the device only takes a reading after one litre of air has been expelled to give a high level of accuracy. Results are then fine-tuned according to temperature. The colour screen indicates whether you pass or fail and also shows actual breath or blood alcohol levels. If the test is failed it also gives an estimated amount of time before a pass would be possible, with a built-in reminder alarm to retest. The accuracy of the AlcoSense Pro has been measured at +0.10%, -0.00% – so it will never under-read and gives a small margin of safety. It also has a built-in database of more than 40 different drink-drive limits worldwide, just select the country or region from the menu and it will set the relevant limits and measurement units. SRP is £149.99.

Slightly cheaper in price, the AlcoSense Excel uses a 64mm2 fuel cell sensor and forgoes the pressure and flow rate sensors of the Pro, but does retain the breath volume sensor to ensure that readings are only taken after one litre of air has been expelled and also corrects for temperature. Accuracy is not quite up to the Pro’s levels at +0.15%, -0.00%, but it also never under-reads. Drink-drive limit settings can be set manually to match local conditions. SRP is £99.99
Both Pro and Excel units can be returned to AlcoSense for recalibration against a police-spec unit after 12 months.
