Highlights
The catalytic DrägerSensors are particularly shock-resistant and have excellent resistance to poisoning. The high product quality and long-term stability ensure low operating costs. Fast response times provide a reliable warning of gas hazards.
Our own design
We develop these sensors with our own engineering knowledge. This way we can assure quality and accurate measurement. This allows them to be utilized to the fullest in combination with our in-house developed Dräger gas detectors.
Shock resistance
The CatEx SR (SR = shock resistant) DrägerSensor is characterised by its particular shock resistance. A fall from great height that exceeds the standard requirements has no effect on the sensor signal. The usual adjustment of the zero point and sensi … More information
tivity required after an impact can be omitted, which saves time and effort.Adjustment is only required if a different fresh air display than 0 is shown after impact from high falling heights.Durable and resistant to poisoning by sensor poisons
Hydrogen sulphide and silicone are known catalytic poisons that may be present in environments with explosive gas. Thanks to an improved pellistor composition, the sensors are highly resistant to poisoning from these substances. The high resistance t … More information
o poisoning leads to exceptional long-term stability, thus ensuring low operating costs.Vapour sensitivity
Unknown gas hazards and higher hydrocarbons pose a particular challenge for the sensitivity display of catalytic sensors. The new CatEx DrägerSensors are particularly sensitive. The detection of all hydrocarbons (from methane to nonane) has been cert … More information

Dräger's catalytic sensors are suitable for providing warning of known and unknown flammable gas hazards. The sensors provide the option of setting the device for a variety of different combustible gases or vapours, including hydrogen. If several fla … More information
mmable substances to which the sensor reacts differently must be measured, a substitute gas adjustment is recommended. Different test gases can be used for the adjustment using a simple device function. The necessary calculations are performed by the gas measuring device. Manual conversions are not necessary.Rapid response times
Rapid warning for explosive gases and vapours is vital. Our CatEx sensors' fast response times minimise the timespan between danger and warning.
Fast adjustment
With the DrägerSensor CatEx SR, fresh air adjustment can be performed after a maximum of only 60 seconds after switching on the device. This saves valuable time and lets you perform a fresh air adjustment shortly before the shift, for example.
From the LEL to 100 vol%
Our catalytic sensors are suitable for measurements in the lower explosion limit range. For methane, measurement up to 100 vol% is also possible.

With the DrägerSensor CatEx H2 100, Dräger also offers a sensor specially optimised for hydrogen applications. With this sensor, measurements can be carried out across the entire measuring range, from a few ppm or %LEL up to 100 vol%. Here too, the o … More information
