Why Choose a BACtrack Professional Series Breathalyzer?

Police-Grade Accuracy, Every Time You Test

All BACtrack Professional Series breathalyzers employ BACtrack's proprietary police-grade Xtend Fuel Cell Sensor Technology and are ideal for applications that demand the most accurate results, such as clinical or roadside alcohol testing or personal BAC monitoring.

Precise, Consistent BAC Results

The linear response of BACtrack's Xtend Fuel Cell Sensor delivers precise results over the complete range of alcohol concentrations expected in the breath, from 0.000 to 0.400 percent BAC and excels in instances where individuals are tested repeatedly in a short period of time

Long-Term Reliability

BACtrack's Xtend Fuel Cell Sensors have an extended sensor life (when compared with other traditional sensors), which allows BACtrack Pro Series breathalyzers to maintain their accuracy for up to thousands of tests, delivering long-term reliability you can trust.

Benefits of Xtend Fuel Cell Sensor Technology

  • Police-Grade Accuracy
  • Precise, Consistent BAC Results
  • Long-Term Reliability
  • Sensitive Enough for High BAC Testing
  • Faster Warm Up Time
  • Longer Battery Life
  • No False Positives

BACtrack Trace Features

Simple, One-Touch Operation

The Trace is easy to use - insert the two AAA batteries that come with the product, and it's ready to test. When you press the start button, the BACtrack Trace counts down for approximately 10 seconds, preparing the system for a breath sample. When the countdown reaches zero, blow steadily and continuously for at least 5 seconds. If a sufficient breath sample has been taken, the user's estimated BAC is displayed on the screen.

Reliable Performance, Accurate Results

Despite its small size, the BACtrack Trace packs serious technology inside its black plastic casing. There is a miniature air pump inside the Trace that activates at the end of each breath sample. You can actually feel the 'click' during each test. This proprietary internal sampling system ensures that a precise breath sample enters the alcohol fuel cell sensor, and is one of the reasons why the Trace provides trusted, accurate results every test.

Test Yourself, Friends and Family

With it's easy to read LCD screen, extraordinary battery life and six extra included mouthpieces, BACtrack Trace is perfect for testing yourself as well as your friends and family. Take it with you wherever you go and gain peace of mind while keeping your loved ones safe with BACtrack.

The Military and Law Enforcement Trust BACtrack

Police Departments rely on BACtrack Breathalyzers as preliminary screening devices during DUI traffic stops to determine if someone is possibly intoxicated. They trust BACtrack because they know they are getting the most accurate BAC results possible.

Semplice e affidabile. Ripetendo più volte la misurazione, questa risulta sempre coerente, per poi scendere , lentamente, col passare del tempo e poi azzerarsi. Lo tengo in auto, se supero i 0,5, faccio guidare mia moglie. Per me è stato un ottimo acquisto.
