Keep an eye on your alcohol level at all times – quickly, easily, and hygienically! The compact alcohol tester from LogiLink provides you with precise results of your breath alcohol concentration in seconds. This way, you can protect yourself from unexpected fines after parties or events. The operation is incredibly simple: insert 2x AAA batteries (not included) and blow into the tester for 3–5 seconds to get your result. All test results, including battery status, are displayed on the LCD screen. If your test result exceeds 0.5 ‰ BAC, an acoustic alarm will sound. After 15 seconds of inactivity, the tester will automatically turn off. Thanks to its compact design with a keychain hole, the tester can be easily attached to keys or stored in bags and purses. Take it with you to weddings, parties, or other social events to ensure you always get home safely.
