Breathalyzer for Alcohol, Portable BAC Tester with Airflow Sensor, Keychain

Breathalyzer for Alcohol, Portable BAC Tester with Airflow Sensor, Keychain

• DUAL-SENSOR SAMPLE CHECK – The air-pressure sensor detects blowing while the semiconductor sensor analyzes alcohol concentration. This helps verify that a breath sample is being provided and clearly separates airflow detection from alcohol analysis.
• SIMPLE THREE-STEP TESTING – Insert a mouthpiece, power on, and wait through the 10-second warm-up. When prompted, blow steadily for 3–4 seconds for a BAC reference reading. Wait 20 minutes after drinking and more than 3 minutes between tests.
• COLOR DISPLAY AND MEMORY – Green, yellow, and red indicators help you scan results. English voice prompts guide the test, while the 99-reading memory lets you review prior results. Double-click power to select g/L, mg/L, or %BAC.
• BATTERY-POWERED KEYCHAIN DESIGN – The approximately 4.61 x 2.32 x 0.75 in body slips into a pocket, purse, backpack, or travel case. It runs on 3 AAA alkaline batteries, not included, so no charging cable is needed.
• WASHABLE MOUTHPIECES – Wash and fully dry each detachable tip before reuse. Keep the tester away from smoke, perfume, and strong odors. Personal reference only—not for medical, workplace, legal, law-enforcement, or driving decisions.
