FIELD OF OPERATION

The BEL-AIR wireless thermo-hygrometer checks room
ambient conditions and outdoor conditions at the same
time and gives a ventilation tip, if opening or closing the
windows will currently improve the indoor climate.

Excessive room-air humidity can damage your health and
promotes the formation of damp patches and mould.
But excessively dry room air can also affect our well-being and
health in various respects. Skin, mucous membranes and
airways are adversely affected and pets, house-plants, wooden
flooring and antique furniture may also suffer.

Checking indoor temperature and humidity and acti ve
ventilation can help achieve a comfortable and healthy
living environment.

If the room air is too humid, ventilation would at first appear
nonsensical in the winter, when the outside ai r is also cold,
damp and just as humid.

Cold air however, can absorb little or no moi sture. When this air
enters the living areas it becomes warmer. And then the air can
absorb much more water vapor. This interdependency of
temperature and relative humidity is considered and calculated
by your BEL-AIR wireless thermo-hygrometer.
