This easy-to-use, accurate Digital Alcohol Detector provides a digital reading of your blood alcohol level within seconds after blowing into the mouth vent. When a breath sample has registered, and alerts you if a complete breath sample wasn't measured. About the size of a lighter, it has a backlit display and low-battery detector. Includes two AAA batteries that last for over 300 uses, and a handy travel pouch. (3 1/2 x 11/4 x 1/2"; 1 oz)

The size of an ordinary writing utensil, our Alcohol Detector Pen is small enough to fit in a pocket and always be at the ready to check your level of alcohol consumption. Toss one in your glove box or briefcase and you'll always be prepared. To use simply take a deep breath and blow into the hole in the end of the pen. If the red light appears, then your alcohol density is over 0.05% and probably unsafe to drive. Don't take chances with your life. Having this affordable Alcohol Detector Pen just might save your life the next time you think about getting behind the wheel after drinking. *Warning Use this product only to indicate the possible presence of alcohol in the blood.
