Cheetah 1 alcohol teste

purpose
It can be used to judge whether to drive after drinking
There are usually two methods to detect drunk driving: one is to detect the blood alcohol concentration of the human body, and the other is to detect the exhaled alcohol concentration
Theoretically, to judge whether to drink driving, we should check the alcohol content in the driver's blood
However, in behavior treatment or routine inspection of highway traffic, it is often unrealistic to draw blood on site
The feasible method is to detect the alcohol content in the exhalation of drivers on site

Expiratory alcohol detector is an instrument to detect the alcohol content in the exhalation of drivers
When using the test, the subject is required to exhale with a mouthpiece
If the subject exhales with moderate strength for more than 3 seconds after deep inhalation, the relationship between the alcohol content in exhalation and the alcohol content in blood is: blood alcohol concentration = exhalation alcohol concentration & times; 2 200。
