NOTICE
Damage to the CatEx sensor!
Fractions of catalytic poisons in the measuring gas (e.g. volatile silicon, sulphur,
heavy metal compounds or halogenated hydrocarbon) can damage the Cat Ex
sensor.
► If the CatEx sensor can no longer be calibrated to the target concentration,
replace the sensor.
WARNING
Risk of explosion!
If the CatEx sensor is exposed to hydrogen and low temperatures (< -10 °C) for
a long time (> 1 h), measured values that are too low may be displayed. This
also applies if hydrogen is being measured but the measured gas set is not
hydrogen.
► The CatEx sensor should be set to the measured gas "hydrogen"for regular
and planned measurements of hydrogen. Measuring tasks which last less
than 30 min. are not affected by this.
Increased hydrogen concentrations within the measuring range of the
