General
The CD2105 utilizes the method of NDIR ( Non-Dispersion Infra-Red ) and measures the carbon dioxide concentration up to 0 – 5000 ppm in the ventilation systems and in door living space. Its measurement range of 0- 5000 ppm covers range required to monitor compliance with ASHRAE or other ventilation efficiency standards. Packaged in a compact, distinctively styled ABS hardened plastic mould enclosure, the CD2105 can be discretely installed anywhere from duct to boiler room, mush room cultivation house, swinery.
The standard 1/2-inch NPT male conduit in the enclosure wiring access and fully floating outputs make installation a snap. The model CD2105 provides several output alternatives. A voltage or 4-20 mA current output is standard. An optional FND 4 digit display readout is available. an optional relay contact can be configured to open or close above a user-adjustable set point. A simple one point calibration procedure and a built-in calibration port that requires no special fittings or adapters make the model CD2105 simple to maintain.
The basic model CD2105 has a single green LED on the front panel which illuminates whenever the unit is operating. This LED is on steady when the measured concentration is below the high limit, and blinks whenever the measured concentration is above the limit
