This breathalyzer can be used at home voluntarily and it will help you not get into any legal hassles and dui violation. After a few beers or a few glasses of drink you would need to know if you are able to drive home at all. For that simple reason alone you need to have a home breathalyzer.

Legal limit for Blood alcohol content

The legal limit for the driving is .08%BAC, though chances are that if you are driving and still not beyond the limits you can be arrested for dui in case your driving is not correct. You can be arrested even if you have .05% BAC. The home breathalyzer cannot tell you whether you should be driving or not. That decision definitely rests with you as an individual though a breathalyzer can help you make that decision.The home breathalyzer will measure the blood alcohol content or the BAC and it will measure that in percentage. It is assumed that alcohol in your breath has a correlation to the alcohol in your blood. The alcohol in the body does not gets digested and is absorbed via the tissues in stomach, throat and mouth. It gradually gets mixed into the blood and the gradually expelled out via the liver or evaporation. 

After every 500 uses you can either recalibrate the breathalyzer or you can have the sensor removed and use a new one.
