Product details
iBACheck pocket alcohol tester with LED display – AAT178
quick snapshot
This neat pocket breathalyser is for anyone who wants a quick, sensible check before getting behind the wheel or making a call after a night out. It uses a semiconductor sensor to deliver fast results on a bright LED display, stores the last 10 readings and runs on 3 x AAA alkaline batteries for plenty of use between changes.
why it helps
Is it worth carrying one? In a word: yes. It takes the guesswork out of deciding whether you’re safe to drive or not. The iBACheck AAT178 flags rising blood alcohol concentration with an audible alert and a clear HI indicator for higher readings. Pocketable, straightforward and no faff—ideal for everyday checks when you want a quick steer rather than a complex bit of kit.
how to use (and what to watch for)
- Rinse your mouth and wait at least 10–15 minutes after drinking, smoking or eating — alcohol in the mouth will skew results.
- Blow a continuous sample for more than 5 seconds; if you’ve just switched the unit on, give the sensor time to warm up.
- Readings tend to settle over 15–30 minutes after drinking; full elimination can take from minutes to several hours depending on the person.
key features and benefits
- Fast semiconductor sensor – gives results in seconds, handy for regular personal checks.
- Memory for 10 recent tests – track changes without scribbling them down.
- Four selectable units (‰ BAC, %BAC, mg/100 mL, mg/l) – useful when travelling or checking different local limits.
- Audible alarm and HI indicator when results exceed the alert threshold (default alert at >0.50‰ BAC; user-adjustable).
- Low standby current and long battery life – around 350 tests on 3 x AAA alkaline batteries (actual life depends on how you use it).
- Compact dimensions (approx. 110 x 46 x 20 mm) – slips into a pocket or bag with ease.

important notes and legal bit
This device estimates breath alcohol concentration and is not a substitute for professional or forensic testing. Driving limits vary by country and region — always check local laws before deciding to drive. If the unit shows a high reading or you’re in any doubt, don’t drive. Readings taken immediately after drinking can be artificially high due to mouth alcohol; wait the recommended time before testing and allow the device to stabilise between tests.
final thoughts
It’s a tidy little tester that does what most people need: quick checks, simple operation and a handy memory. It’s not police-grade, but it’s a practical, portable tool for everyday safety — a useful bit of kit when you want to make a sensible choice after a night out.
