【New & Unused】Alcohol Checker Alcohol Detector (USB Rechargeable) 【Blow-Type - Safe Non-Contact】 Just breathe into it to measure! It's healthier and safer than direct-entry types. An essential item to prevent drunk driving. It's crucial to actively use it before driving, after drinking, or in the morning after a party to prevent excessive drinking and drunk driving. 【High Performance & High Accuracy】 Our alcohol checker uses a high-performance semiconductor gas sensor, which can prevent strong interference. When turned on, it automatically eliminates excess air and ensures accurate detection in a short time. You can easily measure by simply blowing into it. Measurement range: 0.0-0.95mg/L. Note: This product is not a device to determine the permissibility of drunk driving. 【USB Rechargeable - Easy to Use】 It can be charged with the included USB cable. It uses USB-C charging, which is more convenient than conventional battery-powered products, and has a longer lifespan. One charge allows for approximately 300 uses. 【Clear Measurement Results!】 The alcohol detector has a light, making it easy to see even in dark places. The contrast is clear, the visibility is high, and it's easy to understand. The warning sound depends on the measurement results: ① "Non-Drinking State": Alcohol concentration value <0.15mg/l, green light turns on. ② "Drinking State": Alcohol concentration value in the range of 0.15mg/l-0.25mg/l, displays the word "Warning", orange light turns on, and a warning sound is heard. ③ "Drunk State": Alcohol concentration value ≥0.25mg/l, displays the word "Danger", red light turns on, and a warning sound is heard.
