Duct carbon dioxide sensor, air quality, relative humidity and temperature


This innovative solution combines CO2, air quality, relative humidity and temperature, offers long-term stability and accuracy for all measured parameters.

The sensor can be used to ensure adequate ventilation, maximizing energy savings through ventilation at the ideal level, making it ideal for all types of ventilation in many applications.

The air quality sensor is a gas mixture sensor with high sensitivity to VOCs such as ammonia, toluene, formaldehyde and cigarette smoke, alcohol, H2S, and carbon monoxide.
