Sober Check

The Sober Check uses advanced semiconductor sensor technology to detect alcohol vapour in your breath. Simply blow into the mouthpiece for 3–5 seconds, and the device instantly analyses your breath sample. The colour-coded LED system delivers immediate feedback: Green means you're sober and safe to drive, Orange indicates alcohol is present (caution advised), and Red means you're over the legal limit. A digital display also shows your precise BAC (Blood Alcohol Content) reading for complete transparency.

Sober Check is calibrated to professional-grade accuracy standards, with a high-sensitivity fuel cell sensor that detects BAC levels from 0.0% to 0.4%. The device is designed to align with South African legal limits and breathalyser standards. For best results, wait 15–20 minutes after your last drink or food before testing, and ensure the device has been calibrated within the last 6–12 months. Regular calibration maintains peak accuracy and reliability.

The Sober Check is powered by rechargeable lithium batteries that deliver up to 100 test cycles per charge — easily lasting weeks of regular use. The device itself is built to last years with proper care. The fuel cell sensor typically remains accurate for 2–3 years of regular use before recalibration or replacement is needed. We provide clear battery status indicators and sensor life alerts, so you'll always know when maintenance is due. Our local SA support team can arrange affordable sensor replacements and recalibration services.

Yes. Personal breathalysers like Sober Check are completely legal to own and use in South Africa. They're designed to help you make responsible decisions before driving. However, note that only official police breathalysers are admissible as evidence in court. Sober Check is a personal safety tool — if you test positive, the responsible choice is to not drive and arrange alternative transport. South Africa's legal BAC limit is 0.05% for drivers, and 0.02% for professional drivers. Use Sober Check to stay well below these limits and keep yourself and others safe.

Your Sober Check package includes: the breathalyser device, a USB charging cable, 10 disposable mouthpieces for hygiene, a quick-start guide, and our local SA support contact details. Getting started is simple: charge the device fully (about 2 hours), insert a fresh mouthpiece, and you're ready to test. The intuitive LED and digital display require no app or complicated setup.
