More Information Than Guessing How You Feel

A BAC Estimate You Can See in Seconds

How you feel is not a reliable measurement of blood alcohol concentration. This compact tester provides an estimated BAC reading directly on its screen so you have more information than subjective guesswork alone.

Use It With or Without Your Phone

Check an estimated BAC directly on the device when you want a simple reading, or connect to the compatible app for additional history and ZeroLine® estimate features.

Device-only when you want simplicity. App-connected when you want additional tracking.

BAC breathalyzer standalone mode and app connected mode

4 Core Benefits

Useful Information in a Device Small Enough to Keep Nearby

Fuel-Cell BAC Estimation

The device uses fuel-cell sensor technology to analyze a breath sample and provide an estimated BAC reading. The result appears directly on the digital display without requiring you to judge sobriety by how you feel.

Breath sample • Digital result • Less subjective guesswork

App History Estimates

Connect to the compatible smartphone app to review past results and access estimates of approximately how long it may take for BAC to return to 0.00%.

Result history • Wireless connection • Estimated return-to-zero time

BAC breathalyzer with and without smartphone

Works With or Without Your Phone

You do not need to open an app just to see a reading. Use standalone mode for a result directly on the screen, or connect your phone when you want added tracking features.

At approximately 2.21 × 1.88 inches, the compact body can stay on a keychain, slip into a pocket or fit into a small bag without taking up the space of a bulky tester case.

Important Safety Information

⚠ Never Use a BAC Reading as Permission to Drive

This product provides an estimate of BAC. It does not guarantee that you are safe, unimpaired or legally permitted to drive. Alcohol affects people differently and legal BAC limits vary by location. If you have been drinking or are unsure, choose a safe ride and do not drive.
