Room Carbon Dioxide Detector
The CDD5 series room carbon dioxide detector uses a highly accurate and reliable non-dispersive infrared (NDIR) sensor to monitor CO2.
Overview
The CDD5 series room carbon dioxide detector uses a highly accurate and reliable non-dispersive infrared (NDIR) sensor to monitor CO2, a precision thermistor to monitor temperature and a thermoset polymer based capacitance sensor to measure humidity levels combined with state-of-the-art digital linearization and temperature compensated circuitry in an attractive, low profile enclosure for room applications and provides 3 analog outputs. Optional set point slidepot, momentary override and adjustable relay output are also available.
