Product Description

Combo PM10 & PM2.5 Sampler

In new air quality standard notified by Govt. of India where measurement of PM10 and PM2.5 dust is required with other pollutants to decide status of air pollution.  So far samplers developed in India do not have provision for simultaneous sampling of PM10 and PM2.5 dust. Thus two samplers need to be operated simultaneously to know concentration of these pollutants in ambient air. This results measurement of these parameters expensive and difficult as significant efforts are required in transport of two samplers and their operation in field.

Ecotech realizes these limitations and took lead to develop  impactors based Combo sampler for simultaneous sampling of PM10 & PM2.5 dust using single instrument.

Single stage impactor matching to European Union designs has been fitted in the Combo Sampler for PM10 measurement. This impactor removes dust greater than 10 microns from ambient air  when sucked through it   at  constant flow rate of 2.3 m3/hr   .

For sampling of 2.5 micron dust two stage impactors based on the USEPA standard designs (published in Federal Register 40 CFR part 50 Appendix L (updated in May 2002)) has been incorporated in AAS 271.This impactor removes dust greater than 2.5 microns from ambient air  in two stages( first in Pm10 impactor and second in WINS impactor fitted in series ) when air is passed  through it at flow rate of 1.0 m3/hr  

Ecotech AAS 271 is fitted with Thomas make world’s best brushless and noiseless pump assembly of adequate capacity to generate needed sampling rates simultaneously for PM10& PM2.5 Impactor. Constant flow rates in both air stream are maintained through out sampling duration with the help of critical orifices. Pump assembly is equipped with heavy duty induction motor which ensures that sampling rate are not affected due to input voltage fluctuations.

AAS 271 is equipped with two digital flow Totalizer for recording exact volume of air sucked through filter fitted at out lets of single and two stage impactors.
