Note:
Polytron 7500 cannot be used with DrägerSensors other than the above
listed. The corresponding DrägerSensor must be used to ensure that the unit
functions correctly.
ATTENTION! Explosion hazard!
Do not operate underground or in explosion-hazard areas!
The Polytron 7500 does not meet the standards for flameproofing and explo-
sion protection.
Not to be used for intake from explosion-hazard areas!
The concentration of flammable substances in the intake air must be limited
to values below the LEL (Lower Explosive Limit)!
The gas mixture may otherwise be ignited because of the high pyrolysis tem-
perature in the Polytron 7500.
Only suitable for use in buildings!
— The measuring range may be selected, but it is dependent on the sensor installed.
— With 4 to 20 mA interface or HART
— Optional: compatible with LON interface for connection to a suitable control unit.
