According to a survey by the World Health Organization, around 50% to 60% of traffic accidents art related to drink-driving. So how do we make sure whether drink driving, and how to determine the level of drinking driver violates the traffic rules? The current hot-traffic cases at the same time cause the curiosity of alcohol tester. Test out the concentration of alcohol in the blood from testing the exhaled gases and can give results in a short time. How does the digital breath alcohol tester do it well in the end?

Test the exhaled gases to define the concentration of alcohol in the blood from

In appearance, new digital breath alcohol tester is not special. It generally consists of a mouthpiece, a tube and a gas chamber that can be formed. Other more advanced equipment if necessary will be different because the instruments are based on different test principles. But only from the operational level, this is truly an amazing thing. Anyone tested only breath deeply to mouthpiece. After ten seconds, it can be shown that someone tested contained concentration in the blood alcohol.

Although the police use kinds of auto digital breath alcohol tester, they work using the same principle. The principle is that the concentration of alcohol in breath and blood alcohol concentration will show a certain proportional relationship. When people drink, the alcohol in the mouth, throat and stomach has been absorbed into the blood at last. But in this process, the alcohol will not be digested by the body. Some alcohol will evaporate through the alveoli, and will be breathed out. This is why people can determine the blood alcohol concentration through testing the gla breathed out.

Three kinds of alcohol tester

Although the tests have the same principle, how to quantify breath alcohol content still is a problem. Different types of testers have completely different approaches. At present, there are three kinds of alcohol testers according to different testing methods. Breathalyzer is a exhaled breath tester using a chemical reaction agent to determine the alcohol concentration. In 1954, an Indiana State Police, Robert • Bekenstein invented the Breathalyzer, which is the world's first alcohol-testing tools. Until today, it is still the most frequently used as the alcohol testing equipment all over the world.

The other two testers were Intoxilyzer and Alcosensor III or IV, Intoxilyzer determines the alcohol content by the extent of alcohol molecules absorb infrared light. And Alcosensor completes the testing using the positive and negative electrodes through the fuel cell. This electrode is made from platinum metals. When the alcohol gas is breathed into the fuel cell, it will make platinum react, resulting in current generation readings.

These alcohol testers are very sensitive. Usually, they are used as a law enforcement tool. But now, it is also the hot products among many drivers. Everyone can buy mini digital breath alcohol tester to test themselves, it also the approach to remind themselves.

But if you drink some, even if a little, you don’t drink your car anywhere anytime. And if you have to drive your car to do something, you don’t drink.
