System Description
The Series 9502 CO2 Monitor features a next generation infrared sensor that redefines the science of infrared gas sensing. The compact and easy to use Series 9502 CO2 Monitor is suitable for applications in HVAC Demand Control Ventilation, Environmental Chambers, Indoor Air Quality, Greenhouse Monitoring, and many other commercial and industrial applications.

The non-dispersive infrared (NDIR) sensor is the focal point of the Series 9502 CO2 Monitor. Unlike electrochemical carbon dioxide sensors, non-dispersive infrared gas sensors do not chemically react with the gas being sampled.  The ability of certain gases to absorb infrared radiation has been successfully utilized in developing various gas sensing instruments. A key advantage factor over traditional IR sensors is the ease in which the Series 9502 can be field calibrated. Its superior design makes field calibration fast and easy. And, because of the high reliability components used in the Series 9502 Carbon Dioxide Monitor, calibration intervals are much longer (years rather than months) than rival devices.

 

The Series 9502 CO2 Monitor comes equipped with an easy-to-see 0.35” high liquid crystal display, single adjustable alarm relay, and a 4-20 mADC linear output that can be used with a recorder, datalogger, etc. In addition to the 4- 20 mADC output, the Series 9502 CO2 Monitor has a  0-10 VDC analog output also. Both analog outputs can be scaled by the user over any low and high values as long as they don’t exceed the range of the monitor.
