PC World recently posted an article on Gadgets That Tackle Tough Problems on their website. The first device was a keychain breathalyzer.
OmegaPoint claims its BreathKey is accurate to +/- 0.01 percent BAC (Blood Alcohol Content) at a BAC of 0.08 percent. On their website they say law enforcement breathalyzers are accurate within 0.005 percent.
The BreathKey is Food and Drug Administration (FDA) certified, meaning it is “substantially equivalent” to other consumer breathalyzers on the market. OmegaPoint emphasizes that the BreathKey cannot be used as proof you’re below the legal BAC limit nor determine whether you’re safe to drive.
BreathKey is one of many keychain breathalyzers available. Other include AlcoHawk, Legal Limit, and Connectables. Prices on Amazon.com range from about $20 up to $70 and features vary.
While a keychain breathalyzer cannot be used in court, if used reasonably, it could help keep you out of trouble. Be aware that many states have lesser drinking and driving laws. For example, Colorado has laws against both DUI and Driving While Impaired (DWAI) . DWAI applies to any driver who is intoxicated, but below the per se limit of 0.08 percent.
