• 【Easy to Use】 Using our breathalyzers is extremely simple. Turn on the device with the power button, wait 15 seconds for warm-up time, then blow continuously for 3 to 5 seconds. After 5 seconds, your alcohol level will appear on the LCD screen; the breathalyzer will then automatically turn off after 15 seconds of inactivity.

• 【Portable Breathalyzer】 Our breathalyzer is more compact than a mobile phone; it therefore takes up very little space in your car or bag. In addition, we provide an elegant storage pouch for even more convenient and secure transport when traveling. Ideal for personal use, professional use, drivers, parties, or family gatherings.

• 【Professional-Level Accuracy】 This breathalyzer is equipped with a high-precision semiconductor alcohol sensor, quickly providing you with reliable and accurate results regarding your alcohol level. It is the ideal choice for portable breathalyzers for people who consume alcohol.

• 【LCD Screen and Light Alarm】 Once the test is complete, the LCD screen displays your exact alcohol level. A green LED indicates a result below 0.8 ‰ (alcohol level), while a red LED signals a result above 0.8 ‰, ensuring accurate interpretation of the results.
