Dewocke professional alcohol tester – portable USB breathalyser with LCD
Here’s a handy little gadget that makes checking your blood alcohol level quick and straightforward. The Dewocke professional alcohol tester is a compact, pocket-friendly breathalyser built for personal and on-the-go use. It’s designed to give clear, easy-to-read results with minimal faff, so you can check yourself before heading home after a night out without any hassle.
what it does
The unit uses a high-sensitivity semiconductor sensor paired with a high-induction chip to estimate blood alcohol concentration (BAC) from your breath. Results appear on a bright HD LCD, and a three-colour indicator — green for safe, yellow for caution and red for over the limit — makes the outcome obvious at a glance. It’s described as “police-accurate”, offering a professional standard of measurement suitable for personal checks (see note on legal use below).
key features
- USB rechargeable battery (300 mAh) — no fiddly battery swaps; just charge with a standard phone cable and keep going for weeks with light use.
- Compact dimensions (approx. 90 × 26 × 25 mm) and lightweight (about 50 g) — slips into a pocket or bag with no bother.
- Fast warm-up (~15 seconds) and a response time under 5 seconds — results when you need them, sharpish.
- Non-contact breath design for better hygiene and repeated use — simply blow for roughly 4–5 seconds.
- Clear HD LCD with warning icons if readings exceed normal ranges, so you don’t have to squint to interpret the result.

use, care and a few things to bear in mind
After switching on, follow the on-screen prompt and blow steadily once the device has warmed up. Wait a short while after eating, drinking, smoking or using mouthwash before testing — residual mouth alcohol can skew results. The tester is ideal for personal checks and gives rapid, reliable indications, but it’s not a substitute for official tests: for legal or medical matters follow local laws and certified breath-testing procedures.
People often ask about calibration and long-term accuracy. Like most semiconductor breathalysers, occasional calibration or professional servicing is recommended if you rely on it heavily. If a reading looks odd, try the test again after a few minutes or have the unit checked professionally.
In short: a neat, no-nonsense breathalyser that’s simple to use, easy to carry and handy for keeping tabs on sobriety — a proper little help when you’re planning a journey or just want peace of mind after a social evening.
