Particulate Sampling Systems

Of all of the pollutants, that are contnuously dispersed into the atmosphere by various sources fine particulate matter has the greatest effect on human health.

PM is defined as a mixture of solid particles and liquid droplets found in the air. It includes “inhalable coarse particles,” with aed larger than 2.5 microns and smaller than 10 microns and “fine particles,” with diameters that are 2.5 micrometers and smaller.

The particles comprising PM may come in many sizes and shapes and can be made up of hundreds of different chemicals. Some particles, known as primary particles are emitted directly from a source, such as construction sites, unpaved roads, fields, smokestacks or fires.

Others known as secondary partciles are formed through complicated reactions in the atmosphere of chemicals such as sulfur dioxides and nitrogen oxides that are emitted from power plants, industries and automobiles. Most of the fine particle pollution in the world is made up of secondary particles.

We manufacture a large variety of PM Sampling Systems for meeting diverse user requirements both in terms of technical and financial constraints.

The parameters which necessitate the variety in our samplers include :

  • Particulate size: TPM, SPM, PM2.5, PM10
  • Sampled Volume / Flow Rate: High Volume, Low Flow
  • Flow Measurement: Conventional Rotameter based, Advanced Electronic Measurement and digital display
  • Flow Control, Accuracy & Record: Automatic Flow Control, Constancy and Out-of-specification record
  • Blower Type: Belt Driven, Direct Driven
  • Data Management: Manual Record & Computation, PC based data retrieval and reporting.
