Breathalyzer Alcohol Tester with Dual Sensor, LCD and 20
Breathalyzer Alcohol Tester with Dual Sensor, LCD and 20 Mouthpieces | Portable personal BAC monitor for home, parties, road trips and travel; color alerts and breath detection simplify each check
Can I test right after a drink or snack?
To avoid mouth alcohol affecting the reading, wait about 20 minutes after drinking or eating. Avoid mouthwash or gum beforehand. Test in fresh air and use the same blowing method each time.
Why do readings vary from test to test?
Readings can vary if tests are back to back. Leave 3+ minutes between tests, and avoid strong odors, sprays, or fumes. Take the test in a calm area and blow steadily.
What’s the correct way to take a test?
Power on, wait about 10 seconds, then blow through the mouthpiece for 3-4 seconds. The LCD shows the result and the light indicator helps you interpret it. For best consistency, test 20 minutes after food or drinks.
What if the screen stays blank or I get “0”?
If there’s no result or it shows "0", ensure you're blowing steadily and for the required duration. If the issue persists, check the battery level and replace if needed.
How do I keep it clean for shared use?
Use a clean mouthpiece for each user. Mouthpieces are detachable and reusable—rinse and fully dry after use. Keep the device dry; don’t wash or open it. Store away from heat, direct sun, and strong electromagnetic fields.
- DUAL-SENSOR BREATH ANALYSIS: The sensing system evaluates a steady breath sample and displays an estimated alcohol reading for personal reference. Suitable for responsible self-checks after dinners, celebrations, festivals or other adult social occasions.
- COLOR LCD WITH AUDIBLE ALERTS: The illuminated digital screen presents the result with green, yellow or red indicators for quicker interpretation, while an audible signal confirms the testing sequence. Measurement units can be switched after a completed check.
- GUIDED BREATH SAMPLE DETECTION: Power on the device, allow the warm-up countdown to finish and blow evenly for approximately 3–4 seconds. Active breath detection can display an error when airflow is too short or inconsistent, helping the user repeat the process correctly.
- DETACHABLE TIPS FOR GROUP USE: Replaceable mouthpieces reduce direct contact when the tester is shared among adults. Its compact handheld format stores conveniently in a glove compartment, travel bag or household drawer for gatherings, vacations and camping trips.
- BATTERY AND TESTING NOTES: Operates with 3 AAA alkaline batteries, which are not included; this model is not rechargeable. Wait 15–20 minutes after drinking, eating, smoking, chewing gum or using mouthwash. Results are estimates only and must not determine whether it is safe or legal to drive.
