Alcotest® 4000 Personal Breathalyser
The Alcotest® 4000 Personal Breathalyser from Dräger delivers police‑grade accuracy in a compact, easy‑to‑use device. With a single button press, simply take a breath and blow — within seconds, the Alcotest® 4000 provides your breath alcohol concentration. Dräger’s trusted sensor technology has been used by law enforcement worldwide for more than six decades.
The mouthpiece is designed for intuitive use and is protected by a hygienic cap. For accuracy and hygiene, a new mouthpiece should be used for each person tested. Additional mouthpieces are available for purchase. The device’s airflow system efficiently channels exhaled air across the sensor, drawing only a small sample for analysis.
