and VOC concentrations:
In party rooms, lounges, fair pavilions and exhibition halls, restaurants, canteens,
shopping malls, sports gymnasiums, sales rooms, and conference rooms.
• Acquisition of CO
2
concentrations:
In ventilation applications of rooms with varying occupancy levels where smoking is
prohibited, such as museums, theaters, movie theaters, auditoriums, office spaces
and school rooms.
NOTES: • The QPM Series Sensors are not designed for use as safety devices,
such as gas or smoke warning devices.

Equipment
Combinations
The QPM Series Air Quality Sensors are suited for use with all types of systems and
devices capable of acquiring and handling the signal delivered by the sensor.
Mode of Operation
CO
2
Concentrations
The QPM Series Air Quality Sensors acquire the CO
2
concentration by infrared
absorption measurement (NDIR). Due to an additional integrated reference light
source, the measurement is always accurate. This reduces service costs as no service
or recalibration is needed.
The resulting output signal is proportional to the CO
2
content of the ambient air.
