ONLINE AMBIENT AIR MONITORING SYSTEM: AS PER CPCB
Applications
To maintain the air quality as per the prescribed National Ambient Air Quality Standards.
Description
The On-Line Continuous Ambient Air Monitoring Station is used for the measurement of PM10 & PM2.5 , CO, SO2 , NOx & O3 in the ambient environment.  It is CPCB / USEPA approved and meets the latest specifications of National Ambient Air Quality Standards.



PM10 & PM2.5 Analysers: Operates on the principle of Beta Ray Attenuation and measures particle mass without the effects of shape, size or color of the Suspended Particulate Matter, ranging from 0 to 5mg/m3 with minimum detection limit 1μg/m3 . The equipment includes a PM10 inlet and PM2.5 WINS Impactor.

NOx Analyser : Operates on the principle of Chemiluminescence method, ranging from 0 to 2000μg/m3 with minimum detection limit 0.5μg/m3

SO2 Analyser : Operates on the principle of UV Fluorescence method, ranging from 0 to 2800 μg/m3 with minimum detection limit 0.5μg/m3

CO Analyser : Operates on the principle of NDIR method, ranging from 0 to 125mg/m3 with minimum detection limit 0.03μg/m3

O3 Analyser : Operates on the principle of UV Photometry method, range : 0 to 2500 μg/m3 with minimum detection limit 0.5μg/m3

HC Analyser : Operates on the principle of Flame Ionization Detector (FID) and Selective Combustion, measures Methane and Non- Methane Hydrocarbons. Range 0-5, 0-10, 0-20, 0-50ppm with minimum detection limit 0.22ppm.

Analyzers are available for measurement of other gases like H2S, NH3 ,VOC, BTX, HF, HCL, etc... All the above analyzers are integrated in a 19" rack cabinet and connected to powerful Data Acquisition System which stores more than 5 years data and software with graphical representations.
