Surface-mounted room CO2 sensors

Our AERASGARD® air quality sensors reliably measure the CO2 concentration of the air. Many devices also record humidity, temperature as well as air quality (VOC). In this way, the entire indoor climate can be effectively monitored and controlled. Get an overview of our product range directly.
