Design does matter: a bigger sensor means bigger electrodes and more electrolyte, hence: faster response higher accuracy more stability longer life

The smart DraegerSensor with embedded micro-chip and temperature element supports sensor recognition, numerous selftest functions, remote calibration and signal compensation over the entire temperature range of typically -40 to +65 ºC.

Catalytic Draeger Sensors for the detection of flammable gases and vapors utilize Pellistors which are based on the catalytic effect. Different sensor versions will suit the most demanding industrial applications. The Ex PR M (PR = poison resistant) contains pellistors, which in the presence of catalytic poisons have a longer lifetime than conventional sensors.
