What Drager breath alcohol testers are and how they work

Drager breath alcohol testers are handheld instruments that sample a person's breath and estimate their breath alcohol content based on an electrochemical reaction in a fuel cell sensor. Drager describes these devices as tools for on the spot screening and evidential measurementDrager, 01/15/2025.

In a typical test, the user or subject blows into a mouthpiece attached to the device. Inside, the fuel cell contains electrodes and a porous medium coated with catalysts. When alcohol molecules in the breath reach the cell, they are oxidized, generating an electrical current proportional to alcohol concentrationDrager, 02/20/2025.

The device's microelectronics process this current and convert it into a numeric reading displayed as a breath alcohol value. The instrument guides operators through the test sequence with prompts and status messages. Drager indicates that its professional devices are designed to store test results and event logs for later reviewDrager, 03/05/2025.

Fuel cell sensors are widely used in modern breath alcohol analyzers because they are relatively selective for ethanol and can provide stable output over many tests. US highway safety information notes that fuel cell based instruments are commonly used by law enforcement for roadside alcohol screening because of this selectivity and compact form factorNHTSA, 11/01/2016.

Drager breath alcohol testers usually rely on disposable mouthpieces to promote hygiene and help control airflow. The manufacturer highlights that components in contact with breath are designed for quick replacement and that operators can use device menus to manage calibration intervals and quality checksDrager, 04/10/2025.

Many professional units include backlit displays and simple keypad controls so that tests can be performed in low light or roadside environments. According to the company, some models also support data export via interfaces such as USB or wireless connections for integration into police or corporate record systemsDrager, 09/15/2024.

For industrial users, Drager emphasizes ease of use, explaining that devices are designed so personnel can perform tests with minimal training, following on screen instructions to obtain a valid sample. The company states that indicator icons and audible signals help confirm correct sampling and test completionDrager, 09/15/2024.
