Duct Air Quality Sensor ANDKALQ-U / ANDKALQ-I is for measuring the air quality in ducts of air-conditioning systems, optionally with 0-10 V or 4-20 mA output. Our duct air quality sensor 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.
Additional options for sensor ANDKALQ-U / ANDKALQ-I (surcharges):
- CO2 sensor,
- display,
- relay.
Alternative sensor versions:
- Modbus Duct Air Quality Sensor ANDKALQ-MD.
