There is no more accurate personal alcohol tester available than the LifeGuard. Wherever and whenever there is the need for personal breath alcohol content (BAC) measurement, LifeGuard is the one to trust.
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.
More important - the LifeGuard is economical. The majority of the personal testers on the market are very low quality and therefore very inaccurate. You are paying good money for bad results! They also have a very short life span or have to be calibrated continually. This means you have to replace them regularly or send them to the manufacturer for repeated calibrations. Because the LifeGuard uses a platinum fuel cell, the LifeGuard is precise and accurate. The units have a long life span and only need calibration once every 12 months, making the LifeGuard a very economical solution for your personal testing needs.
The LifeGuard comes complete with a permanent (fold-away) mouthpiece, 10 disposable (slip-on) mouthpieces, 9V battery, wrist strap, nylon carry pouch, operations manual, and one year warranty.
