Duct Mounting Air Quality Sensor, Selectable Output 0/10Vdc or 4-20mA
£324.00 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).
