Description

Alcohol tester

[Technical Field]

The present invention relates to the field of alcohol testing devices and, more particularly, to an alcohol testing device.

【Background technique】

The alcohol tester works by using the electrochemical principle to select an alcohol sensor that is sensitive to alcohol. The alcohol sensor encounters a rapid change in the conductivity of the alcohol molecule to generate a voltage or current signal. The signal is amplified by the circuit and then operated by a dedicated integrated chip. The result of this change after processing is displayed on the tester.

Using the alcohol sensor, the characteristic alcohol tester can quickly detect the blood alcohol concentration of the human body after drinking.
