Electronic Breathalyzer, Breathalyzer, LED Lighting Breathalyzer, LCD Display Breathalyzer, Professional Breathalyzer for Home Use (No Blow Tube Required)

Professional Breathalyzer: What you get: 1 breathalyzer, 1 USB data cable, 1 user manual. The breathalyzer has high sensitivity and high accuracy. After drinking, you can quickly measure your blood alcohol level before deciding whether you want to drive.

High-Precision Alcohol Tester: This alcohol tester uses a high-quality, highly sensitive sensor that is stable and interference-free. No mouthpiece is needed, and the blowing is contactless, making the measurement healthier. Test range: 0.00% ~ 1.9% BAC / 0.0 ~ 1.9 g/L. (Can be about 10 cm from the mouthpiece; simply blow firmly.)

Easy to Use: The breathalyzer has one button. Press and hold the power button to turn it on. Blow for 5 seconds after it has preheated for 10 seconds.

After hearing the beep, the test result is displayed (the "off" indicator flashes twice and the beep sounds twice to signal that the device is off). Lightweight and portable: The handheld meter is small and easily fits anywhere in your purse or pocket. It comes with a USB cable that allows you to connect the breathalyzer to a USB port for fast charging. Ideal for weddings, parties, festivals, or other social events to help you determine if you are fit to drive. Friendly tips: You can take multiple measurements, and the average value is the accurate result. After consuming alcohol, it is recommended to wait 20 minutes before testing to ensure accuracy. This is because it takes approximately 20 minutes for alcohol to enter the bloodstream from the digestive system. Please wait at least 3 minutes before taking the next test.
