Modbus Indoor Air Quality Sensor ANDRALQ-MD for measuring the air quality in living and office spaces etc. The ANDRALQ-MD 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-MD (surcharges):
- active potentiometer,
- passive potentiometer,
- CO2 sensor.
- Modbus sensor
