Air quality sensors monitor several important factors that affect indoor air quality – carbon dioxide levels, humidity, and temperature. A CO2 sensor should be installed wherever there is an increased number of people, such as in schools, communal areas, or office buildings, but also in homes. It reliably alerts you to stale air and the need for ventilation.

A high concentration of CO2 in the air is referred to as stale air and causes headaches, fatigue, and impaired concentration. In enclosed spaces with a higher concentration of people, this condition occurs quite commonly, as CO2 is a product of breathing, as well as combustion, fermentation, and other biochemical processes. In places such as incinerators or wine cellars, the concentration of CO2 can reach life-threatening levels, and the detection of this gas is mandated by law. A CO2 sensor triggers an alarm when the concentration of this gas increases. Thanks to the display, you will always have a perfect overview of the air quality in the room. In addition to precise values, some CO2 sensors also feature different coloured backlighting, with each colour indicating a different level of danger. Room CO2 sensors are designed for installation directly in rooms, while duct sensors are for installation in pipes (e.g., air conditioning). Our range also includes sensors measuring the concentration of fine dust particles and volatile organic compounds (VOC).
