Suspended Particles upto 100 microns have emerged as the most critical among all the criteria air pollutants & is caused by number of sources like:-

1 Large, medium & small-scale industries
Road dust construction activities, house hold fuel cooking, waste burning, vehicular emissions etc.

In order to control the pollution, it is necessary to periodically monitor the air to determine the extent of pollution and to identify the source of emission SLEHUS123 is designed to meet these needs. This model confirm to guidelines of Central Pollution Control Board.


The high volume air sampler collects suspended particulates on large filter paper. The name high volume is appropriate because the sampling flow rate has a high level of 20 to 60 standard cubic feet per minute (SCFM). Because of the high flow rate, large quantities of particles ranging from 0.1 to 1 gram are collected over a typical 24-hour sampling period. This facilitates gravimetric and chemical analysis and is the advantage high volume samplers have over other air sampling methods.
