Air Monitoring System

Swan Environmental Pvt Ltd offers an on-line continuous ambient Air Monitoring Station for the measurement of PM10 & PM2.5, CO, SO2, NOx and O3 in the ambient environment. This is CPCB/USEPA approved and meets the specifications of National Ambient Air Quality Latest Standards. PM10 & PM2.5 analysers: operates on the principle of beta ray attenuation and measures particle mass without the effects of shape, size or colour of the Suspended Particulate Matter 3 ranging from 0 to 5mg/m3 with minimum detection limit 1?g/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 2000?g/m3 with minimum detection limit 0.5?g/m3; SO2 analyser: operates on the principle of UV Fluorescence method, ranging from 0 to 2800 ?g/m3 with minimum detection limit 0.5?g/m3; CO analyser: operates on the principle of NDIR method, ranging from 0 to 125mg/m3 with minimum detection limit 0.03?g/m3; O3 analyser: operates on the principle of UV Photometry method, range – 0 to 2500 ?g/m3 with minimum detection limit 0.5?g/m3; and HC analyser: operates on the principle of flame ionisation 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. Analysers are available for measurement of other gases like HS, NH, VOC, 2 3 BTX, HF, HCL, etc. All the above analysers are integrated in a 19" rack cabinet and connect to powerful data acquisition system, which stores more than 5 years data and software with graphical representations.
