The breathalyzer has recently gained popularity as a personal use device. While police departments all over America have been using personal breathalyzers for years, the Internet has made it easy for anyone to buy one. The basic functionality of a portable breathalyzer is simple to understand; it detects alcohol on its user's breath, and reports back an approximate BAC of the user. This is used by different consumers for a variety of tasks.
One of the most common uses of a breathalyzer is as a drunk driving deterrent. The devices are kept to quickly assess whether a person who is drinking can legally drive. Many people bring their own personal breathalyzers with them to bars for this reason, and some bars have even begun keeping breath analysis machines at their locations. A variety of breath analysis machines have been developed for this purpose, and they come with a range of features. Many do not require a mouthpiece to be switched out between uses, and some are small enough to fit in a pocket or on a key chain. There have even been special portable breathalyzers designed to work with certain electronic devices. It is worth noting, however, that while portable breath analyzers are very accurate, they are
not necessarily as accurate as police breath analyzers, so users should take care to avoid driving with any amount of alcohol in their system.
There have been some news reports of personal breath analysis machines being used as a gauge for drinking games and contests. As one might expect, this is not a typically accepted usage of a breathalyzer, and it can be very dangerous to engage in such activities. Excessive amounts of alcohol can have serious consequences for drinkers, and a breath analysis machine is designed specifically to curb this type of activity, not to facilitate it.
There are also scientific uses for breath machines in any experiments that require an accurate measurement of a person's inebriation. However, scientific breath analyzers are often far more accurate than those used by police or by regular consumers.
As the cost of breath analysis machines can vary, some are better suited for consumers looking for a very general idea of their BAC, while others are intended only for professional law enforcement. Some are suited to multiple users, while others are strictly designed for personal use. In any case, the ease of use and instant feedback of breath analysis machines will probably keep the devices around and popular for many years.
