DUCT AIR QUALITY SENSOR – KALQ-U/KALQ-I
KALQ-U/KALQ-I
Anwendung
For measuring the air quality in ducts of air-conditioning systems, optionally with 0-10 V or 4-20 mA output. The RALQ-U/RALQ-I is a VOC/mixed gas sensor The CO2 equivalents are derived from a conforming algorithm as the odor emissions are overlaying the CO2 value (see graphics). Long-term drifting and operational deterioration can be eliminated by regularly running the automatic calibration.
