The small alcohol tester is ideal for on-the-go: compact and easy to use. Our alcohol tester has a measurement range of 0.1 g/l. It is perfect for a quick self-test to be on the safe side. After blowing into the sensor for six seconds, the approximate alcohol content appears on the display. The measurement results are shown both as a numerical value and in the form of a traffic light display, optionally in g/l or mg/l. The sensor is designed for up to 1500 measurements, and the remaining lifespan of the sensor is also displayed. Thanks to the internal memory, up to 50 values can be stored. The alcohol tester is powered by AAA batteries, which are easy to replace and widely available.
