The BreathKey Breathalyzer keychain breath alcohol tester shows that big things can come in very small packages. It is the smallest and lightest personal use breathalyzer in the world. It shares one thing in common with a professional breathalyzer used by law enforcement agencies; it uses fuel cell sensor technology. Its accuracy has been certified by the FDA to be used as a personal breathalyzer.

The first thing you notice about this breathalyzer is that it looks a lot like a car door lock remote that you might already have on your keychain. It is extreme light and small, but that does not mean that it is not a powerful breathalyzer. It weighs less than an ounce, but it is powerful enough to detect alcohol in your blood with all the accuracy of the ones law enforcement use.

The reason it is as accurate as the professional use models is that it uses the same technology that makes the professional grade breathalyzers so accurate; fuel cell sensor. This also makes the lifetime battery last so long. With the BreathKey, you would not have to worry that the battery would be dead when you really needed it.
