The purpose of the alcohol detector, what is the standard of the alcohol tester drunk driving

A breathalyzer is an instrument that detects whether and how much alcohol is ingested by the human body.

Legal Analysis: The standard for drunk driving of the alcohol tester is that the blood alcohol content of the vehicle driver is greater than or equal to 20mg 100ml and less than 80mg 100ml. According to the provisions of the "Blood and Breath Alcohol Content of Vehicle Drivers and Testing", drinking and driving refers to the blood alcohol content of vehicle drivers greater than or equal to 20mg 100ml and less than 80mg 100ml|driving behavior.

Drunk driving refers to the driving behavior of the driver of a vehicle with a blood alcohol content greater than or equal to 80mg 100ml.

Legal basis: "Road Traffic Safety Law of the People's Republic of China" Article 91 Anyone who drives a motor vehicle after drinking alcohol shall have his motor vehicle driver's license suspended for six months and shall be fined not less than 1,000 yuan but not more than 2,000 yuan. Those who are punished for driving a motor vehicle after drinking alcohol and drive a motor vehicle after drinking alcohol again are to be detained for up to 10 days, fined between 1,000 and 2,000 RMB, and have their motor vehicle driver's license revoked.

If a person drives a motor vehicle while intoxicated, the traffic management department of the public security organ shall restrain him until he sobers up, revoke the motor vehicle driver's license, and pursue criminal responsibility in accordance with law; A motor vehicle driver's license may not be re-obtained within five years.

Anyone who drives a commercial motor vehicle after drinking alcohol shall be detained for 15 days, fined 5,000 yuan, have his motor vehicle driver's license revoked, and shall not re-obtain a motor vehicle driver's license for five years.

Anyone who drives a motor vehicle while intoxicated shall be restrained by the traffic management department of the public security organ until he sobers up, and the driver's license of the motor vehicle shall be revoked, and criminal responsibility shall be investigated in accordance with law; A motor vehicle driver's license shall not be re-obtained within ten years, and after the motor vehicle driver's license is re-obtained, a motor vehicle shall not be driven.

If a major traffic accident occurs after drinking alcohol or driving a motor vehicle while intoxicated, and a crime is constituted, criminal responsibility shall be investigated in accordance with law, and the motor vehicle driver's license shall be revoked by the traffic management department of the public security organ, and the motor vehicle driver's license shall not be re-obtained for life.

Brand model: Mega for alcohol tester.

System: Jiulingling No. 1.

Alcohol tester principle: When an oxide with n-type conductivity is exposed to the atmosphere, it will reduce the number of electrons inside it due to the adsorption of oxygen and increase its resistance. Subsequently, if a particular reducing gas is present in the atmosphere, it will react with the adsorbed oxygen, thereby increasing the number of electrons in the oxide, resulting in a decrease in oxide resistance.

Semiconductor-oxide sensors analyze gas concentrations based on changes in this resistance.

A breathalyzer is an instrument used to detect whether and how much alcohol is ingested. It can be used as a detection tool for traffic police to detect how much alcohol drivers drink when enforcing the law, so as to effectively reduce the occurrence of major traffic accidents; It can also be used on other occasions to detect the alcohol content in the exhaled breath of the human body to avoid major losses of personnel and property, such as enterprises that prohibit alcohol from working in some high-risk fields.

Operation method: 1. Press the power switch, the instrument performs internal self-test and preheating, and displays a countdown from 200 to 0, which lasts 20 seconds.

2. At the end of the timer, an audible prompt will be issued, and the green light will be brightened at the same time, and the yellow light in the middle will flash, indicating that the instrument is normal and the test can be started.

3. Blow the tube at the air intake hole for 4 seconds, if alcohol is detected, the buzzer will alarm, and the red and green lights will flash at the same time. After another 4 seconds, the concentration data will be displayed, if the concentration is between and , only the green light will flash; If it is greater than or equal to , only the red light flashes, accompanied by a rapid sound alarm. The instrument display changes to off after holding the concentration data for 15 seconds.

Note: Due to the extremely high sensitivity in this display mode, if there is residual alcohol gas in the instrument, there will be a tiny digital display. ）

4. If no alcohol is detected from the blowing or no test is done within 30 seconds after turning on, the instrument display changes from 000 to off.

5. When the instrument shows off, you need to start the measurement again.

1. It is recommended that the test is best after 20 minutes of drinking. This is because it takes about 20 minutes for the alcohol to be absorbed into the bloodstream through the digestive system, and it takes about that long for the remaining alcohol in the mouth to dissipate.

2. Avoid testing in a windy environment or a closed room with dirty air.

3. Do not blow the smoke of the cigarette into the instrument, this will damage the sensor, it is recommended to wait for 1 minute after smoking before testing.

4. It is forbidden to blow smoke into the air hole, and the liquid can not enter the air hole, and do not block the air hole.

5. The yellow light indicates that the power supply voltage is low and the battery needs to be replaced.
