The Draeger Sensor Catalytic Ex-Sensors measure multiple gases at the same time–combustible gases and vapors in the air.
Resistance to poisoning
Dr?ger Sensors are robust and easy to handle, and with the Draeger Sensor CatEx PR Technology, we have succeeded in developing particularly long-term stable catalytic Ex sensors. Hydrogen sulfide and silicones are known catalytic poisons which may be present themselves in the environment where explosive gases exist. Thanks to a new pellistor composition, the sensors are highly resistant to ?poisoning? from these substances.
Sensitivity to vapors
Unknown gas hazards and higher hydrocarbons pose a particular challenge to the display sensitivity of catalytic sensors. The new CatEx 125 PR and Smart CatEx (PR) sensors have such a sensitivity. The detection of all hydrocarbons (from methane to nonane) has been confirmed with a measurement certificate for the device series Dr?ger X-am??1/2/5000 and Draeger X-am??7000.
From LEL to 100 % by vol.
