|Innovative and discreet, this FDA approved personal breathalyzer key chain keeps you easily informed of your blood alcohol level so you and your friends stay safe and responsible...even after that terrific birthday bash! Small enough to fit in your pocket, this personal breathalyzer also includes a timer to keep track of your parking meter and a powerful LED flashlight for those dark parking garages and alleys.
How it works: Sanitary and nearly fool-proof, simply blow into the top sensor for three seconds and test results are immediately shown via the colored LED indicator system. The Personal Breath Alcohol Tester will give you a close reading of your blood alcohol level, using a color-coding system to tell you whether or not you should give up the keys. A green LED means your blood alcohol level is below 0.02% - Safe. Yellow means 0.02% - 0.05% - Warning. Red and Yellow - above 0.05% - Danger!
Making for a safer night out, the gadget is easy to carry on your key chain, and includes count-down and count-up timers, as well as an LED flashlight torch function.
