Duct CO2 Transmitters
CDD 24-series
The Carbon Dioxide transmitter CDD 24 is a duct CO2 transmitter series designed to be installed in HVAC return air ducts.
The CO2 sensing element uses the Non-Dispersive Infrared Technology (NDIR) with the patented self-calibration system to guarantee the long term stability and up to 15 years life time.
Options:
Humidity output
Temperature output
LCD display

Carbon Dioxide (CO2 ) transmitters IP65
with infrared sensor CDD and CDB-series
Carbon Dioxide CO2 transmitters with two-beam infrared sensor for the continuous monitoring of the ambient air to detect carbon dioxide concentrations.
The infrared measuring method with integrated temperature and drift compensation stands for highest accuracy, selectivity and reliability despite of the calibration interval of 5 years.
The Carbon Dioxide CO2 transmitters possesses a standard analog output (0)2-10 Vdc or (0)4-20 mA, and an RS-485 interface. 2 relays with adjustable switching thresholds as well as an integrated display are available as options.
Wide selection of measuring ranges:
- 0-2000 ppm
- 0-5000 ppm
- 0-5% vol.
- 0-20% vol.
