According to the survey of the World Health Organization, it’s about 50% ~ 60% traffic accidents involving a drunk driver in the world. So alcohol breathalyzer testers are more and more popular. Typically, they are used as law enforcement tool, but now, it is also hot among many common drivers. After all, buying a alcohol tester is a way of self-alert. That’s because it can test out the concentration of alcohol in the blood from the exhaled breath, and also can give results in a short time.

When people drink, the alcohol is absorbed, but will not be digested, a part of the alcohol evaporates out through the alveoli, in vitro re being exhaled. It was determined that th ratio of the alcohol concentration in exhaled breath and the alcohol concentration ratio in blood is 2100:1, it means that the amount of 2100ml alcohol in breath, is equal to 1ml alcohol in blood. With this ratio, through measuring the alcohol of driver’s breath, traffic police can soonly calculate the alcohol content in blood. If there is no “help” of the alcohol tester, the police only through blood tests or urine tests to determine whether the driver drink or not, but this inspection will outlay of 1-2 days.
