Duct Mounting Carbon Dioxide Sensor with 0/10Vdc Output
£283.50 Exc. VAT
The self-calibrating microprocessor-controlled duct air-quality sensor is used to determine air quality based on a mixed-gas sensor/VOC sensor. It is used to measure air quality and to quantify room air pollution caused by contaminating gases. The air quality sensor does not trace concentrations of individual gases, but assesses the mixed gas concentration. Detectable gases: mixed gas, vapours of VOCs, cigarette smoke, automobile exhaust gases, human exhalation, combustion smoke (from wood, paper, plastics).
CO² transmitters can be used in a broad range of applications including air quality monitoring in buildings. CO² concentration levels in buildings are monitored to provide an indication of occupancy and to drive a ventilation control strategy. An effective DCV (Demand Controlled Ventilation) strategy will conserve energy and maintain indoor air quality.
Specification
Measurement Range:Â Â Â Â Â Â Â Â 0-2000 PPM factory calibrated
Duct Air Velocity:Â Â Â Â Â Â Â Â Â Â Â Â 0 to 450 meter/min
Temp Dependence:Â Â Â Â Â Â Â Â Â Â Â 0.2% of full scale per ËšC
Stability:Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â < 2% of full scale over the life of the sensor (15 years typical).
Accuracy:                     ± 40ppm +3% of reading @ 22˚C (72ºF) when compared with a factory-certified reference.
