Renz Air2Color CO2 Traffic Light Sensor [Pack of 25]



Too much carbon dioxide (CO2) in the room air affects our concentration, our physical well-being and our health. The Renz AIR2COLOR - CO2 traffic light evaluates the quality of the room air on the basis of the CO2 concentration. The surrounding light band makes the air quality visible in the colors green, yellow and red and thus animates to active and effective ventilation. Demand-oriented ventilation reduces the aerosol concentration in the air and also has a positive effect on energy costs.
