SPECIAL OFFER – save £80 on the AlcoDigital 3820!


£ ex VAT

Usual price £299


We are offering all employees of our existing corporate customers the opportunity to benefit from a significant discount on our latest state-of-the-art personal breathalyzer – the AlcoDigital 3820.


Most evidential breathalyzers produced by Draeger will cost you around £1,000 to buy – a huge financial outlay for anyone who would like to test themselves for extra peace of mind. Draeger has created the 3820 to provide a simplified and easy-to-use personal breathalyzer for individuals – at a fraction of the cost of an evidential device.


The AlcoDigital 3820 uses the same technology, and highly accurate police-grade sensor as used in Draeger’s evidential devices, but it can be yours for a fifth of the price.


Usually priced at £299, you can purchase this extremely reliable and highly accurate device for a limited time only for just £219! Not to be used in conjunction with any other offer.


Watch the video below to see all the features of the AlcoDigital 3820.

Over 60 years of advancing breathalyser technology has lead to this incomparably efficient and accurate AlcoDigital 3820 breathalyzer, made by renowned police breathalyser manufacturer Dräger.

It offers responsible drivers a reliable way to test their breath alcohol and gives them the assurance of being legal to drive. This is ensured by precise measurement technology identical to that used by the police.

AlcoDigital 3820 Breathalyser made by Draeger

  • Quick and easy to use – ready in less than 5 seconds
  • Exactly the same sensor as the one used in UK police force breathalysers, an ultra-low energy 220sq mm fuel cell sensor
  • Same accuracy as UK police breathalysers
  • 5 year battery life
  • 2 year warranty
  • Made by renowned breathalyser manufacturer Dräger

Fast and easy sampling

The measurement function is simply activated with the back-lit function button. Optional audible feedback provides additional orientation. The Alcotest 6820 is ready to use in seconds and the breath test can be performed immediately. The same button is used to navigate through the menu.

Replaceable Mouthpieces

The mouthpiece is intuitive to fit and protected by a cap click for source. A new mouthpiece should be used for each person being tested. Additional mouthpieces are available as accessories. The air channel passes the exhaled air over the device, and only a small sample of this air is drawn for analysis. This ensures that there is no residual alcohol in the device and that all measurements remain precise and reliable. The same method is also used by the Police.
