LifeGuard Personal Breath Tester

LifeGuard Personal Breath Tester


LifeGuard Personal Breath Tester

Portable breath testers using fuel cell technology have been in widespread professional use for over 25 years in law enforcement, the workplace, corrections, and related markets where alcohol abuse is a serious individual or public safety and health concern.  LifeGuard, for the first time, makes this highly reliable technology available to the consumer at an affordable price: a trustworthy breathalyzer for serious users who need to rely on the accuracy of their test results. Personal breath testers can be divided into two types by the different technology used to measure breath alcohol content: platinum fuel cell technology and semiconductor technology. Lifeloc platinum fuel cell technology is appropriate for precision breath alcohol content (BAC) measurement. Semiconductor technology is not.

LifeGuard combines precision fuel cell technology, ease of use and reliability into a consumer breathalyzer that stands above all others in personal use and in testing those you care about. The LifeGuard comes complete with a permanent (fold-away) mouthpiece, 10 disposable (slip-on) mouthpieces, a nine-volt battery, a wrist strap, a nylon carry pouch, an operations manual, and a one-year warranty.
