Room CO2 and air quality transmitter

The CO2 and VOC transmitter SACV series measures the presence of carbon dioxide and mixed gases in the room in the range between 0...2000 or 0...5000 ppm. The measurement of CO2 concentration happens through a NDIR sensor that operates on an infrared basis and which compensates the presence of any impurity. The product can be provided with humidity or humidity/temperature sensor. Output 0 ... 10 V DC or 4 ... 20 mA outputs.
