【Semiconductor sensor & Caution】Advanced semiconductor sensing technology can detect alcohol content in seconds. Please wait 15 min. before checking, otherwise the reading will fluctuate from very high to low (then gradually decrease). This is due to the residual alcohol inside the mouth which enhance the result
