Duct sensor for measuring carbon dioxide levels – KACO2/MD

KACO2 sensor reliably detects the concentration of CO2 in the air ducts in the range 0-2000ppm or 0-5000ppm to choose. Measurement results can be displayed via the Modbus. CO2 level measurement is performed by means of NDIR-sensor that works on infrared basis and using a double-beam measuring principle compensates different pollution. Optionally, the sensor can be purchased with an optional module for measuring temperature and humidity.

Duct air quality sensor – KALQ/MD

The sensor is used to determine the quality of the air in ventilation ducts and technical facilities. Measurement results can be displayed via the Modbus. Mentioning the channel sensor of air quality it means VOC/-a detection sensor of the mixed gases. By means of the corresponding algorithm in the device CO2-equivalent is displayed as the smell emission covers CO2 value (see tab.). Continued drifting and ageing of the air quality channel sensor caused by the operation can be eliminated by regular automatic calibration.
