Based on the catalytic bead principle

The catalytic Catalytic Bead DrägerSensors are based on the catalytic bead detection principle, the only detection principle for combustible gases such as hydrogen that is acknowledged in the industry.

Catalytic Bead DrägerSensors Ex HT M

The Catalytic Bead DrägerSensors Ex HT M contains PR pellistors and has been approved for temperatures of up to 150 °C.

Catalytic Bead DrägerSensors ExPR M

The Catalytic Bead DrägerSensors Ex PR M contains pellistors that show longer endurance under the influence of poison substances than conventional types.

Catalytic Bead DrägerSensors Ex LC M

The Catalytic Bead DrägerSensors Ex LC M contains PR pellistors that allow for the detection of very low gas concentrations by their special arrangement and the amplifier electronics. The measuring range is 0…10 % LEL.
