CO2 detectors - Comet
Sensors, detectors and alarms of CO2 concentration 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.
