Disposable Alcohol Breath Testers

Disposable alcohol breath testers are the most inexpensive form of breathalyzer, however, you can only use these items once. Disposable breathalyzers are very inexpensive at only a couple of dollars per test. These items usually come as small tubes filled with crystals that react to set levels of alcohol in the breath. To operate the item the inner tube must be broken allowing the gases from the breath to enter the crystal chamber. The person then blows into the tube.

If the set level of alcohol is exceeded then the crystals will change colors to indicate that the breath alcohol content level has been exceeded. These devices come with a range of breath alcohol content levels, including .02, which detects any traces of alcohol in the breath, .04, .05, and .08.

The benefits of disposable alcohol breath testers are that they are cheap, compact, and easy to use. These disposable breathalyzers also do not require batteries or re-calabration, which provides additional savings. Further, these tests do not react to gases other than alcohol.

The drawbacks to disposable alcohol breath testers are that they do not provide a specific readout of the alcohol content in the person’s breath, and some fear that they may not be accurate enough to tell someone whether they are within a specific legal limit.

A typical keychain mini-breathalizer with stop watch and LED light.

You’re not going to find many breathalyzers smaller or less expensive than the GTMax. However, you will find breathalyzers with more detailed features if you are willing to pay more. This item is a great example of the keychain mini-breathalyzer.

The Keychain Alcohol Tester is 80 mm long and retails for only $10.99. Rather than using numbers that indicate the amount of alcohol in the blood system this device uses traffic lights to indicate the blood alcohol content. A green light indicates a blood alcohol level below .02, a yellow light means the alcohol content is between .02 and .05 and you should wait to drive, and a red light means that the user is has a blood alcohol content above .05 and that person should not drive.

The GTMax has a range of .00 and .19, has a test accuracy of .01, and uses two AAA batteries. The device also features a stop watch and LED flashlight.

It is important to note that police have warned against using such simple breathalyzers, though this item does make a novel gift for a friend.

There are several vendors on Amazon where you can purchase the GTMax mini keychain breathalyzer.
