Breathalyzers

Had a few drinks? Feeling a bit drunk? Not sure if you should drive and risk a drink driving charge? You can buy a personal alcohol breathalyzer test to see if you are over the legal limit. One major problem with most breathalyzers is non specificity; the machines not only identify the ethyl alcohol (or ethanol) found in alcohol beverages, but also other substances similar in molecular structure. Breathalyzer is a trademark used for a device that detects and measures alcohol in expired air so as to determine the concentration of alcohol in a person's body. Online vendors supply breathalyzers and alcohol detectors and testers as well as calibration and other drunk driving information. A breathalyzer is a machine that estimates blood alcohol content (BAC) from a breath sample.
