BEST FOR INDIVIDUAL OR BUSINESS- Our breathalyzer is the best and most accurate devices for an individual or business purchase because they deliver a high degree of reliability. NO FALSE POSITIVES- At higher BAC concentrations, the breathalyzer offers more accurate readings than traditional semiconductor sensors and they are also not subject to false positives when used by diabetics or those on a low-calorie diet. MORE SENSITIVE THAN OTHERS- Breathalyzerrely on an electrochemical process that oxidizes the alcohol in a breath sample and produces an electrical current that the breathalyzer measures to determine the BAC, it’s more sensitive than semiconductor breathalyzers. MORE ACCURACY- Our breathalyzer is carefully designed to exclude ambient air, fumes, and other airborne gases that could contaminate results which deliver the most accurate and consistent BAC results. QUICKLY&EASILY ESTIMATE- Breathalyzer is a portmanteau of breath and analyzer and our breathalyzer can quickly and easily estimate your blood alcohol content (BAC) from a breath sample with more accuracy.
