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.

  • 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. 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.

Technical Specifications:

Discreet and compact but with the same fuel cell sensor technology as professional devices used for evidential workplace and police testing; the 3820 is the ultimate personal breathalyser.
