Description
The CDD-Series Carbon Dioxide (CO2) transmitters are equipped with a two-beam infrared sensor (NDIR) for continuous monitoring of ambient air to detect CO2 concentrations. The infrared measuring method, with integrated temperature and drift compensation, ensures high accuracy, selectivity, and reliability with a calibration interval of 5 years.
The CDD-Series transmitters feature a standard analog output (0)2-10 Vdc or (0)4-20 mA, with RS-485 Modbus communication as an option. Additional features include relays with adjustable thresholds, an integrated display, and other customizable options.
