Product Description

Combo PM10 & PM2.5 Sampler

New air quality standard notified by Govt. of India where measurement of PM10 and PM2.5 dust is required simultaneously 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. Thus measurement of these parameters become expensive and difficult as significant efforts are required in transportation and operation of two sampler at one place.

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 have 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 ) Air is sucked through it at constant flow rate of 1.0 m3/hr  

Ecotech AAS 271 is fitted with one of the best brushless and noiseless pumps of adequate capacities to generate needed sampling rates for PM10& PM2.5 streams. 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 flow meter which continuously display sampling flow rates of two streams controlled by orifice.

Modular design of sampler, tubing and other fitments made this sampler simple easy to transport & operate can be used successfully in harsh Indian climatic conditions


Flow Rate       PM10                  : 38 lpm (Constant Flow Maintained with the help of critical orifice


                      PM2.5                 :16.7m3/hr  (Constant Flow Maintained with the help of critical orifice)

Particle Size                             :Particles of 10 microns and below collected on standard glass micro fiber                filter paper of  47mm diameter fitted below single stage impactor. While particles of 2.5   microns  are collected in a separate 46.2 mm diameter PTFE membrane filter fitted at the   bottom of WINS impactor of two stage  impactor.

PM10 impactor                          : Single stage matching to European Design (according to EN12341)

PM2.5 Impactor                         : Two stage as per USEPA  Published Designs(Federal Register 40 CFR part 50)

Flow Record                          :Independent Flow Indicator for PM10 & PM2.5  streams to display air sampling flow rates passing through filters accurately.

Cabinet                                     :Two part modular, corrosion free, lockable & easy to transport.

Operation                                  :Up-to 28 hours continuously
