Portable breathalyser keychain – professional-grade BAC tester
Want a quick, no-fuss way to check whether it’s safe to drive or get a taxi after a night out? This compact TzzToiT breathalyser clips to your keys and gives a clear result in seconds. It’s designed for personal reassurance rather than official or police testing, but it’s a handy bit of kit for everyday use.
What it measures
The unit uses a new generation of high-precision nanosensors to measure blood alcohol concentration from 0.000% up to 0.400%, with readings shown to three decimal places. Results appear within seconds, so there’s no hanging about or faffing around with complicated setups.
How to use
Dead simple and straightforward—even if you’re a bit bleary-eyed. Typical use goes like this:
- Fit a clean mouthpiece made from food-grade PP.
- Press and hold the start button until the screen lights up, then press again when prompted.
- When the display says BLOW, take a deep breath and blow steadily for about five seconds.
- Read the BAC value and check the three-colour indicator to see whether you’re safe, cautious or over the limit.
Key features
- Clear IPS display with a three-colour warning system – green for safe, yellow for caution and red for danger – so the result is obvious at a glance.
- Smart sobriety time reminder estimates when your BAC may return to 0.00% — handy for planning journeys or knowing when to rest longer.
- USB rechargeable battery so you don’t need to keep buying replacements; charge from any USB port and you’re good to go.
- Lightweight, pocketable design that doubles as a keychain – slips easily into a pocket, bag or glovebox.
- Ten washable, reusable mouthpieces included for hygienic testing with friends or family.
