What our customers are saying

We like to enjoy a couple of drinks when we go out for dinner. Now we can without the worry of DUI.

Super fast shipping. Received within 24 hours. What a great quality product!

Our ED relies on accurate patient diagnosis to make critical decisions. We choose BACtrack.

Peace of mind for both us and our kids. The app allows us to check that they are safe. Thank you.

Love the accuracy. Exact same as the roadside test when we were pulled over. It’s so reliable.

We have zero alcohol tolerance. We partner with BACtrack and are committed to a safe workplace.

Who knew we would finally grow up and become sensible? Eliminating risk is a no brainer.

Everyone should have a breathalyser who consumes alcohol, it is not a luxury item, it’s a necessity

I have an interlock and I don’t want to make the same mistake again. Now I have certainty.

Our company specialises in the operation of heavy machinery. We have entrusted BACtrack for years.

Proprietary Sensor Technology.
Unparalleled Precision.

Every BACtrack breathalyser is engineered around the two factors
that most influence accuracy: sensor type and breath capture.


Xtend® Fuel Cell Sensor Technology

Engineered by BACtrack from technology used in experimental vehicle fuel mixing, our proprietary Xtend® Fuel Cell Sensors deliver the most accurate, consistent BAC results.


Optimal Breath Capture

Breathalyser test accuracy begins with an optimal breath capture mechanism. BACtrack breathalysers’ design is to stop ambient air, fumes, and other airborne gases that can contaminate alcohol test results. 

All BACtrack pro-grade models feature a miniature solenoid air pump to test only air from the deep lung area to enhance accuracy.

Product Information

  • Xtend® Electrochemical Fuel Cell Sensor (Grade 9): BACtrack’s police-grade sensor is the same technology trusted by hospitals, clinics, and law enforcement, and offers the highest level of accuracy consistency.
  • Optimal Breath Capture: Mini-solenoid pump internal breath pump ensures the most accurate and efficient breath capture for alcohol testing.
  • One-Touch Operation: Power on your BACtrack S80 Pro and begin breath alcohol testing in seconds.
  • Advanced Features: Including continuous temperature checking which ensures breath sample consistency.
  • Linear Response: The fuel cell’s linear response provides more accurate results over the complete range of alcohol concentrations expected in the breath. The S80 Pro will accurately measure trace concentrations of alcohol right through to 0.400 %BAC.
  • Acetone: The BACtrack S80 Pro is not subject to interference from acetone. People on low-calorie diets or diabetics have a higher presence of acetone.

Accuracy Focused Engineering

We focus on our technology, so BACtrack’s Pro-grade series consistently outperforms.

Precise Results

The Pro Series’ Xtend® Fuel Cell Sensor Technology’s linear response provides precise results over the complete range of alcohol concentrations expected in the breath, from 0.000 to 0.400% BAC. BACtrack prograde can accurately detect trace amounts of alcohol and reliably handle very high BACs.


Pro-grade models produce the most consistent and reliable results. For example, they are more likely to show the same test result when someone is tested repeatedly in a short time. It means pro-grade BACtracks easily handle multiple high-frequency tests.

High BAC Testing

Pro-grade models are consistently accurate at higher BAC concentrations. Suppose someone is very intoxicated, for example, at 0.22% BAC. In that case, these models are more likely to provide an accurate test result than semiconductor models, which are less accurate at higher BAC values.

No False Positives

The BACtrack S80 Pro will not show a false positive due to acetone’s presence for someone who has diabetes or on a low-calorie diet. Additionally, pro-grade models will nooffer a false positive due to airborne contaminants, which semiconductor models can misread, leading to inaccurate results.

Long-Term Reliability

Extended sensor life helps pro-grade models maintain accuracy for up to thousands of tests, delivering long-term reliability.

Faster Warm-Up Time

Pro-grade BACtrack models like the S80 Pro offer a faster warm-up time, a benefit when conducting high volume and back-to-back tests.

Longer Battery Life

Low power requirements enable up to 1,500 tests on one set of AA batteries.
