Whether it be for peace of mind or educational purposes, an alcohol tester is perfect many different situations. Typically referred to as a personal breathalyzer or  portable breathalyzer, these devices have evolved over the years to the point that you can own one that will give you the same results as those that are used by professional law enforcement and medical personnel.

While alcohol testers come in a wide range of prices and styles, it is easy to figure out which one is best for you. The first thing you have to do is decide what your main reason for wanting a breathalyzer might be. Just as the price range of these devices is very wide, so is the quality level when it comes to accuracy of results.

If you are simply looking for something to use at social gatherings for a bit of fun, or even as an educational tool, you can get a decent unit for less than $50. This is definitely not the kind of breathalyzer you should be keeping in your car and relying on to check your blood alcohol content (BAC) after you have had a couple of drinks. Deciding when you are too impaired to drive is serious business and should not be taken lightly. If that is the reason you are purchasing a blood alcohol calculator you have to understand the differences in quality and price.

While there are some breathalyzers that cost several hundred dollars, there is really no reason for the average person to ever spend that much money on one of these devices. For a little over $100 you can have a very high quality breathalyzer in car for those times when you have had a drink or two and just want to be safe. These units will give you results to the second or third decimal point, depending on the unit, and those results will match any results produced by a breathalyzer used by law enforcement or medical people. In this way you can have confidence and peace of mind when making an important decision like when to drive or more importantly, when not to drive.

When it comes to narrowing down the breathalyzers that are best for you, there is no better way than by reading breathalyzer reviews. These are reports by people who have actually used the product you are considering. It makes sense to know both the good and bad points so you can make an informed decision. Responsible alcohol use includes knowing when to take steps to keep yourself and others safe. Using a breath alcohol tester is a great step towards that goal.
