Greystone CDD4 Carbon Dioxide Detectors with Analog Output

The CDD4 Series CO2 transmitter uses a highly accurate and reliable Non-dispersive Infrared (NDIR) with state-of-the-art digital linearization and temperature compensated circuitry in an attractive, low profile enclosure for room applications and a duct mount version to detect CO2 levels and provides a linear analog signal output of 4-20 mA, 0-5 or 0-10 Vdc signals. An optional LCD display is available that is fully programmable to show only the parameters required.
