The Alcograd breathalyzer allows you to know if you exceed the legal limit for driving a vehicle in just a few minutes!

No calibration required

Easy-to-use breathalyzer: after pressing both ends to pierce the aluminum, simply blow 2 times for 10 seconds at the place indicated by the arrows. After 4 minutes, compare the color obtained with the color scale. Depending on your alcohol content, the crystals will be white (0.00), pale pink (0.02), medium pink (0.05) or purple (0.08).
