AQT-2000-Duct series Air Quality (VOC) Transmitters for Duct
AQT-2000-Duct series
Our AQT-2000-Duct series are designed for measuring the air quality in ducts of ventilation systems, optionally with 0-10 V or 4-20 mA output.
The AQT-2000-Duct has 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 below). Long-term drifting and operational deterioration can be eliminated by regularly running the automatic calibration.
