Single-Use Alcohol Tests vs Digital Breathalysers: Which Should You Choose?
If you’ve ever asked:
“Am I still over the limit?”
You’re not alone.
Many drink-driving charges happen the morning after — not the night of drinking.
Alcohol leaves your body at around 0.015 BAC per hour, meaning you can still be over 0.05 long after you stop drinking.
Sleep doesn’t fix it. Coffee doesn’t fix it.
Time is the only solution.
But guessing is risky.
That’s why more drivers are using a breathalyser to check before driving.
Here’s the difference between your two main options.
Option 1: Single-Use Alcohol Tests
Single-use alcohol tests are disposable devices designed for quick, one-time checks.
Ours are commonly stocked in:
-
Liquor stores such as Liquorland, Superliquor, Blackbull, The Beer Spot etc
-
Bars
-
Petrol stations
-
Events and festivals such as Synthony
Alcolyzer’s advanced single-use alcohol test is TÜV-certified and designed for simple, reliable indication before driving.
Best For:
-
Occasional drinkers
-
Event hosts
-
Glovebox backup
-
High-turnover retail
Pros:
✔ Affordable
✔ Compact
✔ No charging required
✔ Easy to use
Limitations:
-
One-time use
-
No digital BAC display
-
Not ideal for regular monitoring
They provide a helpful indication — but aren’t built for ongoing accuracy.
Option 2: Digital Fuel Cell Breathalysers
For regular drivers, a digital fuel cell breathalyser offers greater precision and repeat use.
Alcolyzer’s rechargeable professional-grade model uses fuel cell sensor technology — the same type used in many professional and workplace testing devices.
Why Fuel Cell Matters
Fuel cell sensors:
-
Are highly specific to alcohol
-
Deliver more consistent readings
-
Reduce false positives
-
Offer better long-term reliability
If your license impacts your job — tradie, fleet driver, sales rep — accuracy matters.
Additional Benefits
✔ Rechargeable long-life battery
✔ Customisable settings (BAC units, language, time and alerts)
✔ Clear digital numeric display
✔ Lower cost per use long term

It’s assuming you’re fine the next morning.
