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. Various precision thermistors or RTD’s are also available to as an optional output.
