The AlcoBlow is a professional, non-contact breathalyser, used to quickly perform a large number of tests. This breathalyser is used by the police and other uniformed services. Thanks to low running costs and very quick measurements, the AlcoBlow is very often used by the police or employers. Testing employees sobriety is particularly important at areas of construction works, at high altitude, and, of course, at shipping and transportation companies, as well as means of public transportation. The measurement takes about 5 seconds, during which the device unambiguously identifies the presence of alcohol in the exhaled air and indicates its low or high concentration. It is not necessary to use mouthpieces, which significantly reduces the cost of operation of the device. In passive mode, the device automatically takes a sample of air and determines whether it contains any alcohol. This allows the operator to quickly check a vehicle cabin for alcohol vapours, and later test the driver or passengers. This is the reason the police is using AlcoBlow as their breathalyzer of choice. With this function, one can also easily verify if a container of "juice" does not actually contain an alcoholic beverage.
