A breathalyzer examines exhaled breath by measuring the concentration of alcohol vapor present. When a person blows into the device, the breath is drawn into a sensing chamber, where a chemical reaction occurs, typically involving a catalyst like platinum. This reaction produces an electrical current that correlates to the amount of alcohol in the breath, allowing the device to estimate blood alcohol concentration (BAC). The results are then displayed digitally for analysis.
