About Alcolyzer

Built for Accuracy. Driven by Safety.

The story behind Australasia’s most trusted personal breathalyser.


Why Alcolyzer Exists

Every year, alcohol-impaired driving claims lives and tears families apart — many of those tragedies are preventable. Alcolyzer was founded on a simple belief: everyone deserves access to a breathalyser they can actually trust.

We set out to bring professional-grade accuracy out of the laboratory and into everyday hands — for the morning after a big night, before a long drive, or whenever you need certainty, not guesswork.

The Technology Behind the H3

Most consumer breathalysers use semiconductor sensors — cheap, but prone to drift and false readings. The Alcolyzer H3 uses a professional fuel cell sensor, the same technology relied on by law enforcement and workplace safety programmes worldwide.

  • Fuel cell accuracy: Electrochemically oxidises alcohol for a precise, repeatable BAC reading every time.
  • Fast and clear results: Clear digital readout in seconds — no waiting, no ambiguity. Plus an easy to read traffic light system takes the guess work out. 
  • Consistent performance: Maintains accuracy across repeated tests, not just the first few.
  • Convenient and practical usability: A compact, pocket sized design with a keyring hole means you can take it wherever you go. 

When you're making a decision that affects your safety — and the safety of others on the road — you need a device that performs like a professional tool. That's exactly what the H3 is.

Our Commitment to You

  • Rigorous pre-shipment testing — every unit is verified before it leaves our hands.

Common Questions

How accurate is the Alcolyzer H3?

The H3 uses a professional fuel cell sensor, which is significantly more accurate than the semiconductor sensors found in cheaper devices. It's designed to give consistent, repeatable readings that you can rely on for real decisions.

Does the H3 need to be calibrated?

Yes — like all breathalysers, the H3 benefits from periodic calibration to maintain peak accuracy. The device is built to support recalibration, and our team can advise you on calibration intervals and service options.

Is the H3 suitable for workplace or professional use?

Absolutely. The fuel cell technology in the H3 is the same class of sensor used in professional and workplace testing environments. It's a reliable choice for health and safety officers, fleet managers, and anyone who needs dependable results.

What's the legal BAC limit in New Zealand?

In New Zealand, the legal blood alcohol limit for drivers aged 20 and over is 50mg per 100ml of blood (0.05% BAC). For drivers under 20, the limit is zero. The Alcolyzer H3 displays BAC readings so you can make an informed decision before you drive.

How long does the H3 battery last?

The H3 is designed for extended use between charges. For specific battery life details and charging instructions, refer to the product page or reach out to our support team.
