About This

• Dual-Sensor Reading System: Uses a two-part sensing setup—air-pressure detection plus a semiconductor module—to capture your breath sample and output a BAC value quickly. This dual approach is designed to improve consistency versus many basic single-sensor personal testers.
• 10-Second Warm-Up, Guided Blow Test: Press power, let it initialize for about 10 seconds, then exhale evenly through the tip for 3–4 seconds. The LCD shows the result right away, and a green/yellow/red status light helps you understand the level at a glance. Tip: For a cleaner measurement, test at least 20 minutes after drinking or eating to minimize mouth-alcohol influence.
• AAA Battery Operation (No Charging Needed): Powered by 3 × 1.5V AAA batteries (not included), so it’s ready anywhere without a cable or dock—useful for parties, travel, and keeping in the car. If the display stays blank, recheck battery direction and swap in fresh cells.
• Pocket-Friendly Size, Comfortable Grip: Compact and easy to carry (approx. 115 × 50 × 25 mm; about 120 g without batteries). Slides into a purse, backpack, or glove compartment for home checks or nights out. Care: Don’t take it apart or rinse/soak; store away from heat, direct light, and strong electromagnetic sources.
• 20 Washable Mouthpieces Included: Includes 20 removable, reusable tips that can be cleaned between users—handy for family sharing, friends, coworkers, or workplace use. For better repeatability, leave over 3 minutes between tests, and avoid sampling near perfumes, fumes, or other volatile odors.
• Troubleshooting & Re-Test Guidance: If results look off or there’s a noticeable sensor odor, run 3+ continuous blow cycles to refresh airflow, then test again in a well-ventilated area. If alcohol appears without drinking, residue or internal fermented gases may be affecting the sensor—clean the device, air it out, and recheck.
