The Alcotest® 4000 Personal Breathalyser from Dräger is designed to measure your alcohol concentration with the same accuracy as police devices. Ensuring responsible driving is as easy as pushing a button, taking a breath, and blowing – in just seconds, the Dräger Alcotest® 4000 provides your breath alcohol concentration. This reliable breathalyser utilizes sensor technology that has been trusted by law enforcement for over six decades!
The mouthpiece of the Alcotest® 4000 is designed to be user-friendly, fitting intuitively and protected by a cap. To maintain hygiene and accuracy, it is recommended to use a new mouthpiece for each person tested, and additional mouthpieces can be purchased if needed. The device’s air channel efficiently passes exhaled air over it, drawing only a small sample for analysis.
