CO2 detectors - Advanced features - Database viewer

Sensors, detectors and alarms of CO₂concentration in the air.

Do you need to measure the concentration of carbon dioxide (CO₂) in the air? For accurate measurements, you can use CO₂ concentration detectors and alarms. The concentration of carbon dioxide in a room is an important indicator for optimal air conditions. Carbon dioxide is an excellent indicator of the air quality in a room. A high CO₂ content has a major effect on a person's concentration and also manifests itself in drowsiness, a feeling of fatigue and can even turn into a headache or nausea. Carbon dioxide is odourless and cannot be recognized by humans.

Alarms and detectors can effectively measure the CO₂ content and can give an alarm if the set limits are exceeded. This allows you to ventilate and change fresh air efficiently.
