Keep an eye on your alcohol level – quickly, easily, and hygienically! This compact breathalyzer by LogiLink shows your breath alcohol concentration within seconds. This way, the tester can save you from fines after a celebration or event. Operation is simple: Install 2x AAA batteries (not included) and blow into the alcohol tester for 3–5 seconds to get the result. All test results, including the battery level, are displayed on the LCD display. If your test result is higher than 0.5 ‰ BAC, an alarm will sound. After 15 seconds without activity, the tester automatically shuts down. Thanks to its compact size with a lanyard hole, it can easily be strapped to keys or carried in a backpack, handbag, or purse. Take it to weddings, parties, banquets, or other social events to ensure you drive safely after drinking.
