Dräger Alcotest® 6820

The fast and compact Dräger Alcotest® 6820 alcohol detection device meets the stringent requirements of professional breath-alcohol analysis. With its tried-and-tested DrägerSensor, this robust alcohol tester guarantees very rapid response times and precise test results in all weather conditions and can also be adapted to international guidelines.

Alcohol tests for increased safety

Alcohol is one of the most common causes of accidents - both on the road and in the workplace. The Dräger Alcotest® 6820 enables you to increase general safety, and help prevent personal injury, material damage, and even the loss of public image that can result from alcohol consumption.

Very easy to use

To deal with a person being under the influence of alcohol requires a high degree of concentration. The Alcotester is easy to use, enabling you to perform breath alcohol tests simply and rapidly. All the measurement functions are operated with just one button. Easily understandable full-text messages on a large, backlit display guide you safely through the alcohol testing procedure. An LED and acoustic signals enhance the visual display and indicate when the test is complete. Two menu buttons are used for navigation and to record the statistical data.

Proven quality

The tried-and-tested electrochemical Dräger sensor is also used in the Alcotest 6820. This sensor features very rapid reaction times, high accuracy and a long service life. Even at temperatures of -5 °C and +50 °C, the analysis is always reliable. And, in case of high alcohol levels, the sensor delivers fast, safe results - with both active and passive detection.

Practical design

The Alcotest 6820 features a user-friendly and ergonomic design. Its compact shape makes it particularly easy to hold, and it can be controlled with one hand. Thanks to its contour, placing the mouthpiece of the Alcotest 6820 in its mount is intuitive, even in the dark. No matter whether it is for use by a right- or left-handed user, or for checking in traffic driving on the left or right, the display is constantly visible to the user. After use, removing the mouthpiece is just as easy and hygienic.

High-quality workmanship

A professional breathalyser has to withstand a lot. Thanks to its user-friendly shape and high-quality workmanship, the Alcotest 6820 meets the growing number of application requirements. And, thanks to its robust materials, it is particularly weather-resistant, e.g. to cold or moisture, and complies with protection class IP 54.

"Slide ’n’ Click" mouthpiece

The patented Dräger mouthpieces prevent any attempts at manipulation. The optional non-return valve also ensures the highest degree of hygiene.

Data processing and documentation

The expanded memory capacity of the Alcotest 6820 can record up to 5,000 test results. An optical interface enables wireless data transfer to the Dräger mobile printer directly on site. In addition, via a USB connection, the data can be transferred to a PC, or the device can be configured.

Optional accessories

​A wide strap makes the Alcotest 6820 secure and convenient to operate. The strap can be secured to a belt or around the wrist with either a buckle or a hook and loop fastener. Reflective strips make it easy to locate the device when necessary.
