Theben CO2 sensors and room air sensors

Room air sensors such as the AMUN CO2 sensor from Theben enable you to improve the air quality in public spaces such as schools, universities or large offices. The CO2 content of the air is constantly monitored, and if the maximum level of 0.1 % recommended in DIN 1946 is exceeded, AMUN switches on the ventilation control or air conditioning.
