INTRODUCTION
Your BACtrack Mobile Breathalyzer is a professional alcohol
screening device used for the detection of alcohol in the
breath. It uses a professional-grade fuel cell sensor to analyze
your breath, then transmits this reading to your smartphone or
tablet via Bluetooth, where your Blood Alcohol Content (BAC)
estimate is displayed.
Your Mobile Breathalyzer is powered by a battery that can be
recharged via the micro-USB cable provided. Simply use the
cord to plug the unit into a USB slot on your computer and
charging will begin. Please note that the USB cord only charges
the device - no data is transmitted

Alcohol and Its Effects on the Human Body
When alcohol is consumed, it is absorbed from the mouth,
throat, stomach, and intestines into the bloodstream. Blood

carries the alcohol throughout the body - including to the lungs.
As alcohol-laden blood moves across the membranes of the
lung’s air sacs (alveoli), it permeates the breath. The concentration
of the alcohol in the alveolar air is directly related to the
concentration of alcohol in the blood.
The ratio of breath alcohol to blood alcohol is generally estimated
to be 2,100:1. Therefore, every 2,100 ml of alveolar air contains
approximately the same amount of alcohol as 1 ml of blood. The
breathalyzer uses this ratio in order to make an accurate estimate
of your BAC.
Alcohol is a Drug
Alcohol is the chemical (ethanol or ethyl alcohol) resulting from
the fermentation of grapes or grain. Alcohol is absorbed directly
into your bloodstream. From your bloodstream, the tissues in
your body absorb the alcohol. Your brain is a tissue made up of a
large concentration of fluids and absorbs a large amount of any
