Low Cost Duct Carbon Dioxide (CO2) Transmitter
General Description
The MCD200LC utilizes the method of NDIR (Non-Dispersion Infra-Red) and measures the carbon dioxide concentration up to 0 – 10000 ppm in the ventilation systems, indoor office, meeting room, living space etc.
Its measurement range of 0- 10000 ppm covers range required to monitor compliance with ASHRAE or other ventilation efficiency standards. Packaged in a compact, distinctively styled enclosure that can be used for living space, meeting room, livestock farm, horticulturam farm, fruit grower, mushroom farm and greenhouse.
The model MCD200LC provides two outputs 4-20 mA and 2 relay contact outputs as standard. The status normal and alarm lamps are available . An optional two relay contacts and alarm setting can be configured by the program using the remote terminal TOTE-BOX TB101.
NDIR sensor is most stable and does not require any recalibration and it use semipermanently for carbon dioxide measurement
