Breathalysers – buy online.  

Personal Breathalysers (Breathalyzers)

When buying a personal breathalyser online there are some critical things to take into consideration to make sure you get the most accurate blood alcohol content (BAC) readings. You can rest assured that all of our breathalysers:


  • Are tested to Australian standards
  • Include Lifetime Support and Service:
    • Free re-calibration (every 6-12 months)
    • Drop and damage? We’ll replace it for 50% off the normal price!
    • Done? We’ll recycle the unit back to the manufacturer.
  • Include free educational tools and information such as:
    • Standard Drink Measure cup
    • Pocket Breathalyser Guide
  • Include a full money-back guarantee.


Some of our breathalysers also have a “memory” so you can recall your readings and develop an understanding of how your own body metabolises alcohol over time - see our MK2 Memory Function Smart Breathalyser Kit.
