Very accurate. Most BACtrack testers use advanced semiconductor sensors and have accuracy levels of ±0.01% at 0.10% BAC. Many BACtrack models provide a blood alcohol level (BAC) reading of one
hundredth of one percent and others a BAC reading of one thousandth of one percent. Some law
enforcement organizations use BACtrack testers as preliminary alcohol screening devices.

How do I use my breath alcohol tester?
For most models, users simply blow through the mouthpiece for 2-5 seconds. The sensors measure the
alcohol level of air in the deep lungs. Testing is most accurate if subjects have not consumed food or
alcohol 15 minutes prior to testing.
Why do I need a breath alcohol tester? Aren’t they just for police?
Alcohol breath testers (i.e. breathalyzers) are a great tool for everyone. People are often unaware of theirprecise intoxication level. Different factors like a person’s weight, muscle mass, and recently consumedfood or beverages all affect a person’s blood alcohol content (BAC). Just because a person may act or seem sober does not mean that they are.
I’ve just blown a 0.08% BAC. I’m safe to drive home, right?
Absolutely not. There is no acceptable level of alcohol consumption that makes it safe to drive. Any alcohol that enters a person’s body can impair reflexes, motor skills, and cognitive abilities.
Does my personal alcohol tester come with a warranty?
Yes, all products are guaranteed by the manufacturer warranty. Please refer to the product order pages for additional information.
How does a breathalyzer work?
Most breathalyzers use one of three technologies to detect alcohol: a spectrophotometer, a fuel-cell
sensor or a semiconductor oxide sensor. Spectrophotometer technology is used in large, table-top breathalyzers often found at police stations. Spectrophotometers work by identifying molecules based on the way they absorb infrared light. The level of ethanol in a sample is singled out and measured, and a subject’s alcohol level can then be determined.
Fuel-cell testers, such as the BACtrack Select S80, offer extremely high accuracy and sensitivity, in addition to being handheld and portable. In over 30 US states, roadside evidential testing is now permitted using testers like these. A fuel cell measures alcohol content by creating a chemical reaction that oxidizes the alcohol in the sample and produces an electrical current. The more alcohol that is oxidized, the greater the current. The current is measured to determine the subject’s BAC.
Semiconductor oxide based testers are relatively new and very affordable. Many BACtrack testers employ semiconductor oxide technology. An ethanol-specific sensor is used to measure the subject’s BAC.
Semiconductor oxide sensors offer many benefits, including low cost, low power consumption and small
size. Many law enforcement agencies use these testers for preliminary screening of DUI suspects.
Semiconductor oxide based testers require calibration service on a more frequent basis (every 200-300 tests or once a year) than fuel cell based testers (a minimum of 1,000 tests or 2 years or more). When used for personal, home and low-volume professional testing, semiconductor oxide models have been proven to perform very well and provide extremely accurate readings.
Who invented the breathalyzer?
Though technologies for detecting alcohol vary, it’s widely accepted that Dr. Robert Borkenstein (1912-2002), a captain with the Indiana State Police and later a professor at the University of Indiana, is
regarded as the first to create a device that measures a subject’s alcohol level based on a breath sample.
In 1954, Borkenstein invented his breathalyzer, that used chemical oxidation and photometry to
determine alcohol concentration. The invention of the breathalyzer provided law enforcement with a noninvasive
test with immediate result reporting that can be used to determine an individual’s level of
BACtrack Breathalyzers was featured on The Dr. Phil Show titled "Under the Influence." Dr. Phil encourages everyone to buy and use a BACtrack. BACtrack was also featured on Oprah's All Stars, The Doctors, and in The Wall Street Journal last year.
