Did you know that
the air in a crowded, poorly
ventilated room may exceed the recommended upper limit of 1000
ppm CO2 in a few minutes?
prolonged exposure will result in
efficiency loss, discomfort, and eventually health hazard?
the power consumption to maintain
adequate ventilation may be 100W per person - large savings
can be made by adapting ventilation to actual demand?
AP CO2 sensor will assist you in
keeping track of CO2
concentration, temperature and relative humidity (RH) variations
adapting the personal load and
airing to actual air quality

We perceive air to be fresh when it is unpolluted, and has
adequate temperature and humidity.
We recognize it - especially when it is
People adapt easily, but coming into a room
from the outside it is easy to decide if a room needs airing.
A consequence of the above is that people
tend to stay too long in low quality air.
It is generally believed that the ability to
concentrate and perform, as well as comfort and spirit, will,
consciously or not, drastically decrease with decreasing air quality.
The most sensitive measure of air quality in
this sense is the concentration of carbon dioxide (CO2).
Fresh air contains approximately 370 ppm (volume parts per million)
CO2, but increases rapidly with an increasing number
of people in a room.
Expired air contains as much as 4000 ppm CO2.
In a poorly ventilated classroom, the
recommended hygienic limit of 1000 ppm may be exceeded already
after 15 minutes.
To maintain this level, each breath must
be compensated with more than 30 liters
(6 gallons) of fresh air.
With the air quality sensor from AP on the
wall, it is possible to control that the CO2
concentration, temperature, and relative humidity are within
tolerable limits, and adapt activities accordingly.
Or the reverse: The AP CO2-sensor
may also be connected to the ventilation system for automatic
control of the air flow.
The CO2-sensor is simple to use,
does not require any calibrations or settings.
