Dräger Alcotest® 4000

​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.

So that uncertainty doesn’t come along for the ride

​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.

Fast and reliable alcohol tester

​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.

Replaceable mouthpiece

​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.

Always ready for use

​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.

Handy and discreet

Thanks to its compact design, the Alcotest 4000 fits into a trouser pocket. Therefore you can take a measurement discreetly at any time – no matter where you are.

Designed for years of use

​The Alcotest 4000 is Made in Germany and meets the highest quality standards. Regular calibration of the device ensures that the measurement technology will remain precise for a long time. The worldwide, regional Dräger service network ensures that you can keep using the device for many years.

Precision for over 65 years: the measurement technology used by the police

​Dräger has been one of the world market leader and professional supplier of breathalcohol measuring devices for the police and industry for over 65 years. The measurement technology in the Alcotest 4000 is identical with that in devices used for highly precise breath alcohol tests.

Consistent advances in technology over six decades have made the Alcotest 4000 incomparably fast and reliable today. As a private user or professional driver you can simply pre-empt unpleasant surprises if your breath alcohol content (BrAC) is checked.

Over 30 million breath alcohol tests are performed with Dräger instruments around the world each year.
