maintenance-free CO2 sensing element (depending on the type) based on optical infrared absorption measurement (NDIR1)
? or with VOC2) sensing element, based on a heated tin dioxide semiconductor
? CO2 temperature (active or passive) and CO2 humidity-temperature multisensor
? No recalibrations required
? Operating voltage AC 24 V or DC 15…35 V
? Signal outputs DC 0...10 V or DC 0...5 V adjustable
? Selectable passive temperature sensing element
1) NDIR = Non dispersive infrared
2) VOC = volatile organic compounds (also called mixed gas)
