IAQ Monitor for Monitoring Indoor Air Quality

HD21-ABE-17 IAQ Monitor is a bench-top/portable instrument for the analysis of indoor air quality.
The measurement of the indoor air qualitiy allows the calculation of the automatic ventilation rate by CO₂ analysis correlate to the real presence of people in the rooms.

Simultaneous measurements of:

Carbon dioxide (CO₂)

Carbon monoxide (CO)

Atmospheric pressure

Temperature

Relative Humidity

and calculation of:

Dew point

Wet bulb temperature

Absolute humidity

Mixing ratio

Enthalpy

These regulations apply to all confined spaces that could be used by people. Kitchens, baths, changing rooms and swimming pools are included, due to their high humidity. With regard to air quality, you should also take into account possible chemical, physical and biological contaminants. The instruments have a wide Dot Matrix graphic display with a resolution of 160 x 160 dots.

The instrument's typical applications are:

Measurement of IAQ (Indoor Air Quality) and comfort conditions in schools, offices and indoor spaces.

Analysis and study of the Sick Building Syndrome, and of the resulting consequences.

Checking the HVAC (Heating, Ventilation and Air Conditioning) system efficiency.

Examination of IAQ conditions in factories to optimize microclimate and improve productivity.

Building Automation checks.
