Eliminates Subjective BAC Interpretation

Its fuel cell sensor also ensures accurate, alcohol-specific BAC readings, meaning it won't pick up traces of non-drinking alcohol substances. A top of the range personal breathalyser, the Stealth leaves no room for second guessing.

Results You Can Trust

Never miss a party with the Stealth’s 500 test capacity. You’ll get tired of drinking soon enough but the Stealth can outlast you and your friends. Have it calibrated every 500 tests or six months, whichever comes first. This product’s praise-worthy reliability and accuracy earned it an Australian Standard AS3547 Certification.


Always There to Guide You

Issues in breath test accuracy can arise from either blowing too hard, too soft, or not long enough. Stealth eliminates this issue with its flow rate sensor, which prompts you to test again with a "Flow" error message if insufficient breath sample was provided. The breathalyser itself is slim and portable, and it comes with a protective soft pouch and hard case so you can bring it along when you travel, too. Whether it's for personal or professional use, the AlcoSense Stealth alcohol breath tester is always there to guide you.


“We already have one of these units and have had it for a number of years. Have just purchased another AlcoSense Stealth to keep in our second car It is a brilliant breathalyser. Highly recommended.”

    trustworthy results

    I have had one of these for approximately 4 years now, and so have a couple of my friends. It has been tested side by side against a police issue very expensive model, and has always been accurate. The best money we have all spent!

    Received & tested

    The response & delivery time was very prompt & efficient.
    The unit itself is easy to use & observations at the time of consumption of alcohol appear to be relative as an indication but unable to determine how accurate it is. Do you have any guidelines that you use for calculations or can you provide a chart that would be indicative of readings ie: as in number of beverages that are consumed in a time frame etc. & how long it takes for alchohol to be out of the system ?

    Don’t rate it, highly inaccurate.

    Purchased this due to the raving reviews, very inaccurate, after 15 minutes of a single standard drink the reading is 0% bac, my partner who’s weights 20kg less than myself read 0% as well, followed all the instructions, it pretty much only reads the alcohol straight from your breathe. Would NOT recommend.

    Hi Kenny,
    Thank you for the feedback. We've received your support request and are in the midst of replying to your email to resolve the issue with you for this unit.

    Stay safe and stress feee!

    I'm not what anyone would call a heavy drinker. After being 100% conviced I was under the limit and using a friends Alco Sense Stealth, I had to have one.
    I was right on the limit .05 - and very shocked!

    I drive to work and am a responsible person so AlcoSense is an essential little gadget. I have peace of mind when I go out now. Highly recommended.
