The CD-P1000-00-00U is a duct-mount CO2 transmitter that features a dual-channel NDIR sensor that measures CO2 levels with an accuracy of ±30 ppm + 3% of the measured value.  It has a 0 ppm to 2000 ppm measurement range, with an adjustable range from 1000 ppm to 10,000 ppm.  It has a 20-second response time and operates at either 24 VDC or 24 VAC, with an IP65 enclosure rating.

The duct mount CO2 transmitter is ideal for monitoring CO2 in HVAC systems, ensuring precise demand control ventilation (DCV), fresh air regulation, and indoor air quality (IAQ) management, and rooftop air handling economizer control systems.  Its dual-channel optics and signal processing provide optimum performance making it suitable for continually monitoring supply or return air measurements.  It also has a programmable CO2 measurement span and a 0 to 10 VDC output signal.

The CD-P1000-00-00U is easy to install on a return air duct with its adjustable probe depth for quick sensor placement.  This directly replaces part number CD-P1000-00-00 Duct Mount CO2 Transmitter.
