Indoor Air Quality Sensor ANDRALQ for measuring the air quality in living and office spaces etc, optionally with 0-10 V or 4-20 mA output. The ANDRALQ 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 ANDRALQ (surcharges):
- active potentiometer,
- passive potentiometer,
- CO2 sensor,
