What Drager Alcotest breathalyzers are and how they work

Drager Alcotest breathalyzers are portable devices that estimate a persons breath alcohol content by analyzing exhaled air through an electrochemical sensor system designed for high specificity to ethanol Drager, 06/01/2024.

The Alcotest series typically uses a fuel cell sensor that generates an electrical signal proportional to the alcohol concentration in the breath sample, which is then converted into a digital reading displayed on the device screen Drager, 06/01/2024.

Professional Alcotest models are designed to be operated with one hand and to guide the officer or safety manager through the test via clear visual and acoustic prompts, including ready signals, breath sampling instructions, and result confirmation messages Drager, 05/15/2024.

Drager indicates that its electrochemical sensors in Alcotest devices are designed to respond mainly to alcohol and to minimize cross-sensitivity to other substances that may be present in the breath environment, which supports their use in challenging field conditions Drager, 06/01/2024.
