The CO₂ Sensor (CL-CO₂) is used for continuous monitoring of indoor air quality in buildings and for subsequent efficient control of ventilation system performance based on carbon dioxide concentration. It is suitable for offices, schools, classrooms, shopping centers, homes, restaurants, fitness centers, commercial properties, etc.

The sensor is used in all spaces where the predominant source of indoor air pollution is the people who occupy them. Why?

Because Carbon Dioxide (CO₂) is a very good indicator of how the air in a given space is being exhaled. It must be said that Carbon Dioxide (CO₂) itself is not harmful to health at low levels. However, as the space is exhaled, the concentration of CO₂ rises along with the concentration of other pollutants (so-called Volatile Organic Compounds – VOC), which particularly cause unpleasant feelings associated with stale air.
