Industrial stacks are the means by which an industrial plants discharge their gaseous wastes into the atmosphere. These gaseous effluents may contain pollutants which may be organic or inorganic in chemical nature and be in may be solid, liquid, or gas in physical form.
Stack Monitoring is an instrumental method or procedure for evaluating the characteristics of the emissions from industrial waste gas streams discharged into the atmosphere.
Effluent measurements and sampling procedures follow specific test methods and protocols to ensure representative and accurate emission data. Test methods are generally pollutant specific, sometimes industry specific. These test methods are formulated and recommended by a variety of regulatory and statutory authorities and jurisdictions such as USEPA, CPCB etc.

Physical Design Highlights :
PEM-SMK20 : consists of a Control Module, a sampling pump, a gaseous sampling arrangement and a set of standard sampling accessories.
Control Module : This module is actually an integrated assembly made by tightly coupling two separate sub-modules (units). One sub-module (unit) is a micro-controller based unit which carries out signal processing, timing, computation and operator interface functions etc. This sub-module is called Electronic Unit.
The other sub-module (unit) houses all devices and sensors which measure the various input parameters required for computation of various derived parameters which characterize the stack emission. This unit is called Measurement Unit.
Impinger Module : This module is required for gaseous sampling, It consists of a foldable stand and a lightweight cooling box. The cooling box, which is made of plastic, has the provision to contain ice for cooling the iimpingers. The cooling box has the capacity to accommodate 4 nos. of 125 ml capacity and 2 nos. of 250 ml capacity glass impingers.
Sampling Pump : Sampling Pump is a very lightweight mono-block dry type pump with a free flow of about 100 LPM.
Standard Sampling accessories : Standard sampling accessories includes Pitot tube, thimble filter holder, thimble pipe, nozzles, stack thermo-couple and interconnecting tubes etc.
