An alcohol tester evaluates whether driving is permissible by detecting the alcohol content in exhaled breath (BAC). Modern devices use high-quality sensors and advanced technology to accurately measure breath alcohol content, delivering reliable results. Compact and lightweight, the tester is easy to carry and can be used anytime. It is convenient for frequent testing in settings such as restaurants, enterprises, and institutions. Tests take only a few seconds and require no special preparation. Use scenarios: - In restaurants, hospitality venues, or similar settings to perform quick checks of staff or patrons after events. - In corporate or institutional facilities for routine safety and compliance checks of employees, contractors, or visitors. - For personal use to verify driving readiness before getting behind the wheel.
