Testing for your own sobriety

Portable breath testing devices are not only available to law enforcement officials testing for drunk drivers, but also to the public. Anyone can purchase breath test devices that will check Blood Alcohol Content. 

There are several kinds of breath test devices, but the most popular on the market today is the digital design. This style is small, fitting easily in a pocket, purse or briefcase, and comes with lights that allow you to see your alcohol content analysis in the dark. 

There is also a version of the digital design that can be connected to your keychain. This type may not be considered as accurate as others, but the style is one of the most affordable of the devices. 

Most police officers use what is called a Breathalyzer Kit. This is a more sophisticated design and is considered by many to be the most accurate, easiest to calibrate, and has longest lifespan. Anyone can purchase this style of Breathalyzer, and some police departments have been known to encourage drivers to buy these in an effort to fight the increasing number of drunk driving related accidents. 

The most inexpensive alcohol content testing device is the disposable kind. Some work through a saliva test and others require a breath test. Either style, however, is inexpensive (some brands cost as little as $3 a piece) and easy to carry. The one drawback for these devices is the increased chance of registering a false positive. 

The cost of alcohol content testing devices can vary widely. Some are several hundred dollars per unit, but others, like the disposable brands, are only a few dollars each.
