Breathalyzer for Alcohol, BAC Tester Breathalyzer for Home, Alcohol Tester

DUAL-SENSOR ALCOHOL BREATHALYZER: This blood alcohol breathalyzer combines a semiconductor alcohol detection sensor with an air-pressure blow sensor. The pressure sensor checks whether the breath sample is delivered correctly, while the alcohol sensor analyzes the sample and displays an estimated BAC reading.
ENGLISH VOICE GUIDANCE & MEMORY: English voice prompts guide you through the testing process. The illuminated LCD displays results in %BAC or mg/L, while green, yellow and red lights provide easy-to-see range alerts. The memory function lets you review multiple previous results.
CONSISTENT BREATH TESTING ROUTINE: Wait 15–20 minutes after drinking, eating, smoking, using mouthwash or applying breath spray. Complete the warm-up cycle, then blow steadily for 3–4 seconds when prompted. If the breath is too short or irregular, the screen displays ERR so you can test again.
GUIDED AIRFLOW SAMPLING: A dedicated intake path directs the breath sample toward the semiconductor sensor. Follow the on-screen blow prompt and provide one steady breath instead of short bursts. Keep the air outlet unobstructed and avoid blowing smoke into the device during operation.
20 MOUTHPIECES & BATTERY SETUP: Includes 20 replaceable mouthpieces for individual use among adults. Requires 3 AAA alkaline batteries; batteries are not included. Avoid low-power carbon-zinc batteries. Readings are estimates for personal reference only and cannot determine whether driving is safe or legal.
