Dräger Alcotest® 6820 for DOT

The Dräger Alcotest® 6820 for DOT provides fast and accurate alcohol test results. This reliable breathalyzer makes it easy to follow DOT breath test protocol. In workplaces regulated by the US Department of Transportation (DOT), sober employees are essential – both for public safety and for the company’s reputation. FOR USE IN DOT-REGULATED INDUSTRIES ONLY.

DOT-specific programming helps eliminate user errors

The Dräger Alcotest 6820 for DOT is specifically programmed to meet DOT rules and regulations, intended to help the collector comply with DOT requirements. Key features created specifically for DOT applications make it difficult for breath alcohol technicians (BATs) to make a fatal flaw that could invalidate a test. The device locks down after a positive test (=>.02) for the 15-minute waiting period required before the confirmation test. In addition, it requires an accuracy check and calibration according to the QAP (Quality Assurance Plan) and locks out if expired. Plus, an automatic air blank is recorded and the air blank results prints along with the test result.

Industry-leading BAT training and support; two-year calibration

​The Alcotest 6820 for DOT delivers quality performance and is backed by unparalleled BAT training, which is essential for all DOT BATs. Dräger BAT training meets the mandates outlined in 49 CFR Part 40.213. Best of all, the QAP for the device requires calibration every two years – which saves you time and effort.

Quick and precise analysis

To save time for all concerned, the Alcotest 6820 for DOT is ready to use in less than 4 seconds and measurement results are displayed in a minimum of 3 seconds. The 1/4" DrägerSensor® is alcohol-specific and provides precise measurement results even under extreme conditions (as low as 23 °F/-5 °C). The Alcotest 6820 for DOT is listed on the Conforming Products List and exceeds NHTSA’s Model Specifications for Evidential Breath Testers.

Easy to use, easy to read

​The Alcotest 6820 for DOT is an evidential breath tester designed to meet the needs of both business owners and third-party administrators. This portable breathalyzer is designed for both right- and left-hand use. All measurement functions are controlled with a single button. The instrument guides you through the breath alcohol test step-by-step with full-text messages on a large, backlit display. An LED indicator and acoustic signals support the visual display and indicate when the test is complete. Two menu keys let you easily navigate the menu and access statistical data and settings. Select Screen Test, Confirmation Test, or Accuracy Check right from the start-up menu.

Slide 'n' Click mouthpiece is simple yet secure
