Who uses the BACtrack S80 Pro?

The S80 Pro is used by a wide variety of professional groups to screen for alcohol intoxication. Law enforcement personnel use the S80 Pro during roadside breath alcohol testing to help determine if a subject may be over the legal driving limit of 0.08 %BAC. The S80 Pro is approved by the U.S. Department of Transportation (D.O.T.) as an Alcohol Screening Device.

The S80 Pro is also used by hospitals, alcohol treatment centers, and schools to quickly and accurately test for the presence of alcohol. In many of these applications, the S80 Pro is being used on many subjects in a row, back-to-back. The S80 Pro is suitable for these types of high volume testing applications because it uses a fuel cell sensor and has a faster warm up time (10-20 seconds) between tests.

The S80 Pro is also sold to consumers for personal use. Because the S80 Pro has received FDA 510(k) clearance, it can be legally marketed and sold directly to consumers for personal use. Families dealing with an alcoholic family member, and persons who have received one or more DUI convictions often use the S80 Pro because of its accuracy and affordable price.



Is this the same type of breathalyzer that police use?

Yes, the BACtrack S80 Pro is sold to and used by law enforcement. The S80 Pro is known as a preliminary screening device. When a police officer pulls over a driver and suspects they may be intoxicated, the S80 Pro can be used to help determine if the subject is intoxicated. The digital test results on the S80 Pro, along with other observed subject tests, help determine if the subject should be taken back to the station for additional testing. Back at the station, a fixed, non-mobile alcohol testing unit may be used to get an even more accurate estimate of the subject's blood alcohol concentration (BAC).



I see breathalyzers on Breathalyzer.net for $50. Why should I spend $149 on the S80 Pro?

The S80 Pro has specific features and technology that help provide more accurate test results. First, the S80 Pro uses a fuel cell sensor (Xtend Sensor Technology). These types of sensors are generally more accurate than semiconductor-based sensors, and also more expensive. The Lifeloc FC Series breathalyzers use fuel cell sensor technology; the starting retail price for these models is $480.00. In addition to increased accuracy on each test, the S80 Pro's fuel cell sensor will remain accurate for a much longer period of time - up to thousands of tests. In fact, using the product regularly can actually help keep the S80 accurate, as the moisture in exhaled human breath is beneficial to the sensor.

The S80 Pro also uses a miniature air pump inside the product to more accurately collect a breath sample. During use, you can actually feel the "click" of the pump collecting the breath sample.



Why is the S80 Pro's Xtend fuel cell sensor technology important?

A fuel cell sensor provides the following benefits:

  • It will not show a false positive for someone who is diabetic or on a low calorie diet. Other semiconductor models will sometimes show a false positive result for these individuals.

  • It provides more accurate and more consistent results as compared with semi-conductor models. For example, with the S80 Pro, you are more likely to show the same test result when you test someone repeatedly in a very short period of time.

  • It will remain accurate for up to thousands of tests.

  • It is more accurate at higher BAC concentrations. For example, if someone is very intoxicated, say 0.22 %BAC, the S80 Pro is more likely to provide an accurate test result as compared to semiconductor models, which often lose accuracy at higher BAC values.



    Can I use the same mouthpiece more than once?

    Yes. Each mouthpiece can be reused by the same person, or, if desired, by more than one person. This is often the case in personal-use or entertainment-use situations. However, for maximum accuracy and to eliminate the spread of germs, it is strongly recommended that professional users dispose of mouthpieces after each test.

    The S80 Pro comes with 50 mouthpieces. Additional Packs of 50 and Packs of 10 are available.



    Can I use the BACtrack S80 Pro for personal use?

    Yes. The S80 Pro is FDA 510(k) cleared for consumer use. The S80 Pro is often a top choice for individuals who have previously had a DUI and have an ignition interlock device in their car. The S80 Pro is approximately the size of a cell phone, and it can be carried in a pocket or purse or stored in a car. It is quick and easy to turn on and operate; no special training is necessary.
