About This

• 【Enhanced Dual-Sensor for Professional Accuracy】 Our breathalyzer features advanced dual-sensor technology (air-pressure + semiconductor) that delivers fast, reliable BAC readings with higher precision than standard single-sensor testers. The air-pressure sensor monitors blow consistency—if you blow too lightly or for less than 3 seconds, the device automatically alerts an error and prompts a retest, ensuring every reading is valid. Ideal for personal safety, pre-driving checks, and daily use.
• 【Quick Test & One-Button Operation】 Simply press the power button, wait 10 seconds for warm-up, then blow steadily into the mouthpiece for 3–5 seconds. Your BAC result appears instantly on the clear LCD digital display with traffic-light color alerts (green/yellow/red) for easy interpretation. No complicated setup
• 【Portable Design】 Powered by 3 AAA batteries (not included), this breathalyzer requires no charging cables—ready whenever you need it. The lightweight, compact body (120g, approx. 115×50×25mm) fits easily in your pocket, purse, backpack, car glove box, or center console. It automatically shuts down 10 seconds after testing to save power and extend battery life.
• 【Includes 20 Hygienic Mouthpieces】Our kit includes 20 replaceable mouthpieces. They are easy to clean and reuse, making this breathalyzer good for shared use among family, friends, or colleagues at parties, weddings, banquets, and other social events. Everyone gets a hygienic testing experience.
• 【Practical Tips for Accurate Results】 For best accuracy, wait at least 20 minutes after drinking or eating before testing, as immediate results may reflect mouth alcohol rather than blood alcohol levels. Wait more than 3 minutes between consecutive tests to allow the sensor to reset. Avoid testing in environments with strong odors, perfumes, or volatile substances. Follow these tips to get consistent, reliable BAC readings every time.
