Portable Breathalyzer Alcohol Tester, Fast Accurate Sensor, Triple LED Smart Alert & LCD Display, with 20 Mouthpieces for Home, Road Trips, Parties

Fast & Accurate Results: Equipped with high-sensitivity semiconductor sensor, this breathalyser delivers accurate blood alcohol concentration (BAC) test results within mere seconds. It supports dual-language display switching between English and Japanese by double-clicking the power button, meeting usage demands for different users. The stable sensor structure minimizes data deviation for reliable daily detection. Smart Triple-Alert System: Built with a three-color LED indicator and audible beeping alarm to classify intoxication levels. Green LED means sober status (0.00–0.3g/L); yellow LED plus gentle beep alerts slight intoxication (0.3–0.5g/L); red LED plus loud alarm warns severe intoxication (>0.5g/L). The layered alert system helps users make safe driving decisions instantly without confusing data reading. Wide Measurement Range & Enhanced Accuracy: Featuring an extended measurement range covering 0.00 to 3.00 g/L, covering all daily drinking intoxication levels. To eliminate accidental detection errors caused by unstable exhalation, we recommend conducting three consecutive tests and taking the average value for ultimate precision. It perfectly matches personal pre-drive testing standards for daily safety checks. Effortless Operation: Complete the whole test in 15 seconds total: power on the device and wait for 10-second automatic warm-up, then blow steadily into the matched mouthpiece for 5 seconds. It supports three mainstream international measurement units including g/L, mg/L and %BAC to fit regional testing standards across different countries. Portable & Energy-Saving: Mini lightweight body fits pockets, car storage boxes and travel bags for easy carrying. Comes with 20 reusable mouthpieces to ensure breath testing sanitation. The breathalyzer adopts auto-shutdown design that cuts power after 10 seconds of inactivity to save battery power. Powered by 3x AAA batteries (not included), ideal for road trips, family gatherings and after-party safety detection.
