Air Quality Monitoring System
Air Quality Monitoring System
In most of the industrial environments, the measurement of quality factors such as PM10 & PM2.5, CO, SO2, NOx and O3 in the ambient environment is essential. The online Continuous Ambient Air Monitoring Station is used in such environments and the AAQMS supplied is CPCB / USEPA approved. It functions as per the latest specifications of National Ambient Air Quality Standards. To accurately address potential water bias and volatile loss, the Dynamic Heating System allows the user to hold the sample temperature at a fixed value or below a relative humidity threshold. PM10 & PM2.5 Analysers Beta Ray Attenuation which is a widely used air monitoring technique employing the absorption of beta radiation by solid particles extracted from air flow. This technique allows for the detection of PM10 and PM2.5, which are monitored by most air pollution regulatory agencies. Physical properties such as shape, size and colour of the suspended particulate matter does not affect the measurements in this technique. NOx Analyzer Chemiluminescence in which the light is emitted as a result of chemical reaction (gas phase titration of nitric oxide and Ozone). The emission of light is measured to find the presence of NOx gas molecules. SO2 Analyzer UV Flourescence spectroscopy in which the target gas absorbs the UV light and emits Visible light. CO Analyzer O3 Analyzer UV Photometry
PRINCIPLE TO MEASURE THE REAL TIME ATMOSPHERE PARTICULATE FOR PM 10 AND PM 2.5
Working
The particulate matter smaller than 2.5 (10) μm is automatically concentrated on rolling type filter film. The β ray produced by irradiator C14 passes through the filter film and is received by detector. The detector consists of photomultiplier, plastic scintillator and counter. As per according to the energy of received β ray, it can realize quantitative analyze the enrichment thickness and work out the PM2.5(10) concentration. Measured gas is extracted by sampling pump with certain flow when measuring.
