Track your B.A.C. – BACTRACK!
The BACtrack®Alcohol Detector is an alcohol screening
device, used for the detection of alcohol in the breath.
The BACtrack provides a digital result, indicating the
approximate BAC (Blood Alcohol Content) of the test
subject. The BACtrack is powered by two AAA batteries
and is very easy to use. Simply turn on the unit and begin
testing in a matter of seconds. However, before you begin
testing, there are a few things you should know. Please take
a moment to read your owner’s manual in its entirety and
familiarize yourself with the BACtrack.
Alcohol and Its Effects on the Human Body
Alcohol is absorbed from the mouth, throat, stomach
and intestines into the bloodstream.
Alcohol ingested by the human body can be detected
in the breath because of its presence in the bloodstream.
Alcohol cannot be digested, and it cannot be chemically
changed in the bloodstream. As the blood flows through
the lungs, alcohol in the bloodstream moves across the
membranes of the lung’s air sacs (alveoli) into the
air. The concentration of the alcohol in the alveolar air
is directly related to the concentration of the alcohol in the
2
1

blood. As the alveolar air is exhaled, the alcohol in it can
be detected by the breath alcohol testing device.The alcohol
concentration in the breath is related to that in the blood, and
because of this, an individual’s BAC can be determined by
measuring alcohol in the breath. The ratio of breath alcohol to
blood alcohol is generally estimated to be 2,100:1. Therefore,
2,100 milliliters (ml) of alveolar air will contain approximately
the same amount of alcohol as 1 ml of blood.
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
fluids in your body tissues absorb the alcohol. Your brain is
made up of a large concentration of fluids and will absorb a
large amount of any alcohol you drink. Your liver eliminates
the absorbed alcohol at its own rate of time and nothing you
eat or drink can speed up the process. Your liver does this
by oxidizing the alcohol (converting it into water and carbon
dioxide). Coffee, food or any other “cure” will not sober you
up. Only time will do that.
How does alcohol affect my body?
Alcohol is a depressant. It has a relaxing effect on the
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
affected.Some vision impairments that occur when you have
been drinking include:
• Narrowing of your eld of vision
• Reduction in your depth perception
• Decreased ability to see in darkness
• Increased sensitivity to glare and a longer time
for your eyes to readjust from the glare
Some mental (brain) impairment can occur when you have
been drinking, including:
• Reduced awareness of danger
• Becoming overly condent and reckless
• Difculty in making decisions
• Reduction in balance
• Slowed reexes
• Impaired judgment
How does alcohol affect my driving?
We can’t emphasize enough how dangerous it is for you
to drink and drive. Your vision and your brain are the
most important factors in driving safely. If you jeopardize
either by drinking, and then you drive, you are likely to be
involved in a serious or fatal collision.

*The effects of alcohol intoxication are greatly influenced by individual variations among
users. Some users will be intoxicated at a much lower BAC than shown above.
**Death can occur at a lower BAC in some individuals.
The generally accepted legal standard for alcohol intoxication in the United
States is 0.08%. However, your driving skills can be impaired at a level of
0.04% or lower. It is never safe to drink any amount of alcohol and drive.

SENSOR CLEANSING
When the breathalyzer is used for the rst time, or if the
unit has not been used for an extended period of time
(3 weeks or more) air borne pollutants may form on the
sensor surface. To maximize accuracy, clean the sensor by
performing 2 tests, allowing it to run a complete cycle each
time, and disregard the results. Whether or not alcohol is
present on the breath for the sensor cleaning doesn’t matter.
After running through the complete testing process twice,
cleansing is complete, and you can test again normally.
PREPARATION
Installing the Batteries
Install two Alkaline AAA batteries in the battery compartment.

OPERATION
Test subjects should wait 20 minutes after eating, drinking,
or smoking before blowing into the BACtrack Breathalyzer.
Failure to wait 20 minutes can provide inaccurate test results
and damage the sensor.
STEP 1: Attach a mouthpiece to the
breathalyzer. It protects the sensor from
droplets from the mouth, which could
damage it. The mouthpiece also ensures
a consistent blowing pressure, therefore
contributing to a more accurate reading.

STEP 2: Press the start button.
The BACtrack will begin a countdown.
STEP 3: When the countdown
approaches 2, begin to inhale a
deep breath.
STEP 4: When the countdown reaches
zero, blow and a line will appear on the
screen. Blow through the mouthpiece
continuously for ve seconds while the
beeps sounds and then stops.
STEP 5: Once the sensor has analyzed
the breath sample, the estimated BAC
value is displayed. NOTE: For most
accurate results, wait one minute between
tests. When testing high alcohol levels,
wait 3-5 minutes between tests.

contain methyl alcohol, isopropyl alcohol or acetone.
These substances may interfere with the results of the test.
7. You cannot use the results of this product in court.
8. Do not use the BACtrack as a tool to determine whether
you should operate a motor vehicle or equipment, or
perform any other dangerous act.
9. Do not drink and drive. Always have a designated
driver when alcohol is being consumed.
PRECAUTIONS VERIFICATION AND CALIBRATION
13 14
The BACtrack is calibrated during manufacture using advanced
alcohol simulation equipment. Known alcohol concentrations
are passed through the sensor to set baseline values for testing.
During testing, the unit compares users’ breath samples to these
baseline values.
The accuracy of breath alcohol testers can fluctuate after six
to twelve months of normal use, depending on the number of
tests performed and operating conditions.
If this product is providing inconsistent test results, is not
providing any test results, or provides unusually high or low test
results, the product should be recalibrated immediately by a
trained professional.
The product should be recalibrated at least every six to twelve
months. If the product is used every day, it may need to be
recalibrated as frequently as every month.
Calibration Instructions
Please visit www.bactrack.com or call 415-693-9756 for
information on how to get your BACtrack Breathalyzer
recalibrated.
During recalibration, a professional technician will reset the
sensor baseline values and also perform a full diagnostic check
to ensure the accuracy and reliability of the product.
