In recent days, I have found for me and for others, that one of 0.5 l has significantly less than 0.5 blood alcohol content after two large beer. It does not matter if after the last sip you wait 10 minutes or one hour. And even if you do not eat at the beer, the statement is true. In addition I have in this regard found no differences between men and women that extent, I was able to confirm a Bavarian Prime Minister who has pronounced once appropriate, but very controversial words for beer consumption at the Oktoberfest. Of course, this statement is based on the confidence in the accuracy of the measured values. I have the alcohol content with the breathalyzer Dräger, a leader in medical measured. Since the unit was delivered freshly calibrated, you can probably trust the values absolutely. A recalibration is required after one year, to the device must be sent, which is probably a bit annoying. The device itself is very handy, very easy to use and each measurement takes only seconds. These must be blown as the alcohol test at a police checkpoint in a tube. Three tubes are included, of course you can buy more. After a measurement, you should clean the tubes. All you need to say really. The device is outstanding and makes the name Dräger honor. Whether the investment is worthwhile but in such an expensive instrument for a private person, remains an open question.
