Surface-Mounted CO₂ Room Sensor

Our AERASGARD® air quality sensors reliably measure the CO2 concentration in the air. Many devices also measure humidity, temperature and air quality (VOC). This allows the entire indoor climate to be effectively monitored and controlled. Get a direct overview of our product range.
