C7110A1010
ROOM AIR QUALITY SENSOR
SPECIFICATION DATA & INSTALLATION INSTRUCTIONS
GENERAL
The C7110A1010 Room Air Quality Sensor is suitable for
measuring air quality in rooms, offices, and production bays.
This mixed gas sensor can be used to control ventilation
plants. It detects unpleasant odors, tobacco smoke, and
vapors emitted by such materials as furniture, carpets, paint,
glue, etc. As proven in practice, this device detects those
substances typically present in air having a poor quality,
some of which may otherwise go undetected by room
occupants, themselves. This sensor has proven itself in
numerous applications over many years.
NOTE: The mixed gas sensor does not measure or indicate
the concentration of individual gases, and thus
cannot be used for the monitoring or control of
specific substances.
