Keep an eye on your alcohol level at all times - quickly, easily and hygienically. The compact breathalyser from LogiLink provides you with precise results of your breath alcohol concentration in seconds. This means you can protect yourself from unexpected fines after parties or events. Operation is very simple: insert 2x AAA batteries (not included) and blow into the tester for 3-5 seconds to get your result. All test results, including the battery level, are shown on the LCD display. If your test result is above 0.5 ‰ BAC, an audible alarm will sound. After 15 seconds of inactivity, the tester switches itself off. Thanks to its compact design with lanyard hole, the tester can be conveniently attached to keys or stored in pockets and bags. Take it with you to weddings, parties or other social events so you can always drive home safely.
