Too much carbon dioxide (CO2) in indoor air affects our concentration, physical well-being and health. It is also a key indicator of adequate ventilation and therefore an invaluable tool in monitoring the exposure risk in schools, colleges, universities, offices and the hospitality sector, such as restaurants and hotels. The Renz AIR2COLOR - CO2 traffic light evaluates the air quality of the room based on CO2 concentration.

AIR2COLOR - Makes air quality visible .
The 360° light band running around the AIR2COLOR shows the air quality of the room in which it is placed in either green, yellow or red, encouraging active and effective ventilation. Demand-oriented ventilation reduces aerosol concentration in the air and has a positive effect on energy costs.
