What is an AlcoTester and how does it work?

An AlcoTester is a device used to measure the alcohol content in a person's breath. It operates based on the principle of breath alcohol concentration (BAC) analysis. When a person exhales into the device, the breath sample is captured and processed. The AlcoTester contains a fuel cell sensor or a semiconductor oxide sensor that reacts with the alcohol molecules in the breath. This reaction generates an electric current that is correlated to the alcohol content in the breath sample. The device then calculates the BAC level based on this electric current. The result is displayed on a digital screen within a matter of seconds. AlcoTester devices are easy to use, portable, and are commonly employed by law enforcement agencies, businesses, and individuals to promote responsible alcohol consumption and prevent drunk driving incidents.
