Duct Sensor for CO2 Measurements ANDKACO2 records the ambient air’s CO2 concentration in air ducts of air-conditioning systems. The ANDKACO2 converts the values measured in the ranges of optionally 0-2000 ppm or 0-5000 ppm into a linear 0-10 V output signal. The CO2 value is measured via the NDIR sensor, which is able to compensate for possible pollution with the help of its 2-ray measuring principle. Optionally, our ANDKACO2 is available with an additional sensor for measuring temperature and humidity.
The duct CO2 sensor can also be installed in high humidity (up to 100%) in the absence of condensation. In the case of condensation, measurements of CO2 in the duct would be incorrect as the liquid would close the slots of the sensor.
Additional options for sensor ANDKACO2 (surcharges):
- VOC sensor (only 0-10V version),
- mounting flange,
- display,
- relay.
Alternative sensor versions:
- Modbus Duct Sensor for Carbon Dioxide Measurements ANDKACO2-MD.
