When it comes to portable alcohol monitoring, convenience and reliability are everything. The RELIANT EMU handheld breathalyzer was designed to make alcohol testing simple, discreet and dependable. Whether it’s required by a court order or used voluntarily for personal accountability.

Portable Alcohol Monitoring Device: Small, Pocket-Sized and Discreet Handheld Breathalyzer

The RELIANT EMU is compact enough to fit in your pocket or purse, making it easy to carry and use wherever you go. Its discreet design allows users to test privately and confidently without drawing unwanted attention — a huge advantage over bulky traditional devices.

Smartphone Breathalyzer Compatibility

The RELIANT EMU is compatible with iPhone 7 or newer and Android phones with at least 6 GB of RAM. For best performance, make sure your phone has available storage space before setup.

The device connects seamlessly to your smartphone through the RELIANT EMU mobile app, available for both iPhone and Android. The app is easy to use and guides you step by step through every test.

When you blow into the handheld breathalyzer, the app automatically records and uploads your test results in real time, making compliance simple and stress-free.

Selfie and GPS Verification

Every test taken with the RELIANT EMU is GPS-tagged and includes a selfie verification using your phone’s front-facing camera. This ensures that each test is performed by the correct person and at the correct location, providing verified results that hold up in court and supervision programs.

Automatic Reminders and Real-Time Data

Forget about missing a test. The RELIANT EMU app sends automatic reminders to your phone so you always stay on track. Each test result is uploaded in real time to the ALCOLOCK web portal, where it can be reviewed instantly by supervising officers or program administrators.

Instant Reporting for Supervising Agencies

Supervisors have access to the secure web portal for live monitoring, but that’s not all.
Johnny’s Interlock also provides daily violation reports and monthly summary reports, ensuring that officers, probation departments, and pretrial programs always have up-to-date information on participant compliance.
