Veederline  offers the CDD5 Series CO2/ humidity/ temperature transmitters featuring three sensors in a single wall mount enclosure for a highly efficient environmental monitoring and control system.
 
The CDD5 Series CO2/ temperature/ humidity detectors employ a highly accurate and reliable non-dispersive infrared (NDIR) thermoset polymer based capacitance humidity sensor and curve matched thermistor combined with state-of-the-art digital linearization and temperature compensated circuitry in a low profile enclosure to monitor CO2, humidity and temperature levels in any space.
 
CDD5 Series CO2/ temperature/ humidity detectors provide a linear analogue signal output of 4-20 mA, 0-5 or 0-10 Vdc signals. An optional fully programmable LCD display will show only the parameters required.
 
The ACLP (Automatic Calibration Logic Program) software utilises the computing power in the sensor’s on-board microprocessor to remember the lowest CO2 concentration that takes place every 24 hours. Once the sensor has collected 14 days’ worth of low concentration points, it performs a statistical analysis to see if there has been any small changes in the sensor reading over background levels that could be attributable to sensor drift. If the analysis concludes there is drift, a small correction factor is made to the sensor calibration to adjust for this change.
 
Greystone now offers a 5-year calibration guarantee on all CDD series wall and duct mount sensors used for CO2 based ventilation control when operated in an environment that can utilise ACLP software.
