Method 201 : PM10

US EPA Method 201A compliant equipment for measurement of PM10 emitted by a stationary source

In-stack measurement of particulate matter (PM) emissions equal to or less than an aerodynamic diameter of nominally 10 µm (PM10) from stationary sources is carried out as per US EPA Method 201A.

In this method, a gas sample is extracted at constant flow rate from the source through an in-stack cyclone which is used to separate PM greater than PM10 and an in-stack glass fiber filter is used to collect the PM10. To maintain Iso-kinetic flow rate conditions at the tip of the probe and a constant flow rate through the cyclone, a set of 11 nozzles are provided. Variations from isokinetic sampling conditions are maintained within well defined limits.

Available Model : PEM - STPM10-X
