The breathalyser Dräger Alcotest® 4000 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: over 30 million breath alcohol tests a year.
The Dräger Diffusion tubes are direct reading systems used for the determination of time weighted average concentrations over the duration of one to eight hours.
