We're pleaseed to introduce our brand new alkoSure F22, which estimates the alcohol in your breath and provides a numeric result indicating your approximate Blood Alcohol Content (BAC). Following the BAC result, the unit will also estimate the time it will take (in the format of HH.MM; hours and minutes) for your alcohol level to reach back to 0.00% (Zero - sobriety!). This Predictive Sobriety Timer feature continues in the background, even when the unit is powered off, and is always ready when you need it. Simply power on the unit again to retrieve the remaining time needed for sobriety. Our goal is to provide you with peace of mind so that you can plan responsibly.
