Track your B.A.C. – BACtrack!
The BACtrack
®
Select S80 Breathalyzer is an
alcohol screening device, used for the detection of
alcohol in the breath. The BACtrack provides a digital
result, displaying an estimate of the subject’s BAC
(Blood Alcohol Content). Before you begin testing, it is
very important to read the entire owner’s manual.
It is also very important to have the instrument calibrated
periodically as recommended on page 13. Failure to do
so may result in readings that are inaccurate.
Alcohol and its effects on the human body
When a person consumes alcohol, the alcohol is
absorbed from the mouth, throat, stomach and intestines
into the bloodstream. The alcohol in the bloodstream
exchanges with air deep in the lungs. The percent of
alcohol in a person’s blood (BAC) is proportional to
the percent of alcohol in a person’s breath (BrAC). The
BACtrack measures a subject’s deep lung air alcohol
level and converts it to the estimated BAC.
“BAC” means Blood Alcohol Concentration. It is
measured in %.

muscles in your body. The muscles of your eyes relax and
lose focus. Your eyesight will become fuzzy and you may
experience double vision. Brain activity is slowed. Your
judgment, reflexes, and coordination are all negatively
