The alcohol tester with a practical key ring for fastening has an optical alcohol value display. A green, yellow or red light shows you how much alcohol you have in your blood. If the alcohol level is more than 0.5, the device with the red light indicates that it is unsuitable for driving. 3 levels with corresponding LED indicator:
- Red light (danger)> 0.05%
- Yellow light (attention) 0.02% -0.05%
- Green lamp (Normal) 0.00% -0.02% . This tester is for reference only and does not replace an official test. Not suitable for official and professional use! We recommend not driving a car under the influence of alcohol.
