​Have you already had one glass of wine too many or is your blood alcohol content still in the green?

Whether there is still residual alcohol in the body is something that people often find out too late. With the Dräger Alcotest 4000 you can test yourself at any time if you are ready to drive. This way, you can be more relaxed when faced with alcohol checkpoints by police or employer. No residual alcohol, no stress.

​Whether after a business lunch, at a party or the morning after: Thanks of the DrägerSensor you always obtain a precise result when measuring the residual alcohol value. The measurement function is simply activated with the back-lit function button. Optional audible feedback provides additional orientation. The device is ready to use in seconds and the breath test can be performed immediately. The same button is used to navigate through the menu.

​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.

​On cool winter nights or a hot summer day: The device is ready for use almost immediately. The temperature range for measurements ranges from -5 °C to +50 °C.
