Our room air quality sensors are designed to measure the air quality in rooms or areas.

The measured content includes VOC, CO and CO2 and can also include humidity and temperature.

We also have a range of fine dust PM2.5 and PM10 sensors.

The sensor outputs are 0...10V or 4...20mA.

Please refer to the relevant data sheets for detailed specifications.
