WARNING
Explosion hazard! To reduce the risk of ignition of a flammable or explosive
atmosphere, strictly adhere to the following warning statements:
Fractions of catalytic poisons in the measuring gas (e.g. volatile silicium,
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, the sensor must be replaced.
In case of measurements in oxygen-deficient atmosphere (<12 vol.% O
the CatEx sensor may show incorrect displays; in this case, a reliable
measurement with a CatEx sensor is not possible.
In an oxygen enriched atmosphere (>21 vol.% O
cannot be guaranteed; remove instrument from the explosion-hazard area.
High off-scale readings may indicate an explosive concentration.
