People who breathe good air are healthier, happier and can achieve more. Too high a concentration of CO2 in the air is often to blame for headaches, dizziness and permanent fatigue.

With the AIRCO2NTROL OBSERVER from TFA, you can check how stale and polluted the air is in rooms where people are present, e.g. schools, offices, public buildings. Timely and energy-efficient ventilation enable you to ensure a healthy indoor climate.

The monitor shows the CO2 content of the room air on its large-format XL display in coloured LED digital lights visible from a distance. Depending on the air quality, the colour of the smileys changes from green and yellow to red. In addition, they indicate the temperature and humidity. The brightness of the display automatically adjusts to the environment.
