Overmax AD-02 professional breathalyser – accurate compact driver tester
Need a quick, reliable way to check whether you’re fit to drive after a drink? The Overmax AD-02 is a no-nonsense, pocketable breathalyser made for everyday use. It gives clear readings, bongs an alert if levels are worrying, and tucks away in a glovebox without any faff.
fast readings and clear alerts
This little unit gets going in no time: around a 30-second warm-up, then a result in roughly 5 seconds. The dual-colour LCD makes the number easy to spot whether it’s late at night or first thing in the morning, and the audible alerts tell you immediately if attention’s needed. No more squinting at tiny digits in poor light.
built for reliability and low running cost
Accuracy matters, and the AD-02 delivers ±0.08‰ across a sensible range of 0.00‰–1.50‰, so it’s ideal for routine pre-drive checks. It also comes with four free calibrations over two years — a proper bonus that keeps readings trustworthy without extra cost. Two replaceable mouthpieces and a protective case are included, so it’s ready to go straight out of the box.
- Useful at the end of a night out or after a house party when you’re wondering if driving is sensible
- Handy for family cars where different drivers want a quick safety check
- Suited to employers wanting a simple screening tool (note: not a police-grade device)

A quick note: this isn’t a replacement for professional or police testing — it’s a personal-use device to help you make sensible choices before you get behind the wheel. Legal alcohol limits vary, so treat the reading as a guide and check local rules if you’re unsure. All told, it’s a practical, portable companion that gives a fast, trustworthy indication when it matters most.
