Help Choosing a Breathalyser

A guide to help you choose the best digital breathalyser for your needs

It is important to remember that alcohol levels can continue to rise after you have consumed alcohol and that the levels may continue to rise after you have performed a breath alcohol test.

Any alcohol in the blood impairs an individuals ability to perform a task and increases the chances of having an accident.

In view of this if any alcohol is detected by the breathalyser, even if the digital reading or the colour change indicates that the level is low, we advise that the individual should not drive or operate machinery.

Access Diagnostic Tests is the UK's longest established independent provider of digital breath alcohol equipment to the professional, healthcare and business sector.

We are not tied to any brand or manufacturer, so breathalyser models on our list have to earn their place based on technical innovation, value, and performance.

Digital breathalyser accuracy - you get what you pay for

  • Fuel cell breathalysers have a greater specificity than semiconductor sensor breathalysers. If you are just looking for a screen this probably won't make much practical difference. If your testing other people it does.
  • For workplace screening, we recommend the Draeger 6820 with a printer, as cheaper models will require a confirmation test if you are screening employees.
  • If you want a top end model for healthcare or personal use, think Alcodigital Platimun or AL7000
  • For everyday personal screening and value consider an AL6000

Breathalysers calibration and service

Over time breathalysers will lose the accuracy set initially at the factory. This is called calibration. To maintain accuracy all breathalysers will need periodic maintenance, either a calibration service or a new replacement sensor module. Models with clip in, clip out sensors can be serviced on site, by yourself, in a matter of minutes with no downtime.
