Particulate CEM for wet gas streams

PCME STACK 181 WS

US EPA PS11 capable ProScatter™ particulate CEM for the extractive sampling and measurement of particulate in saturated wet gas streams  

  • Robust design with no moving parts in the optical system
  • Available for use in high-temperature or corrosive stack conditions and Ex hazardous zones
  • Easy to fit multi-patterned flange
  • Adjustable monitoring depth to ensure sampling in the most representative part of the flow path
  • For use as PM-CPMS or PM-CEMS that need to comply with US EPA PS-11
  • ProScatter® technology offers enhanced measurement due to reduced cross-sensitivity of particle type and size
  • Features automatic zero and upscale checks that fully challenge the system’s ability to measure forward-scattered light and satisfy daily drift checks
  • Easily audited with manual filters
  • Stacks after bag filters, cartridge filters, cyclones, electrostatic precipitators, no filtration
  • Non-condensing / dry flue gases
    Typical Applications:

  • Incineration
  • Metals (eg Steel/Aluminium)
  • Minerals (eg Cement/Gypsum)
  • Chemicals (eg Detergent / Carbon Black)
  • Power Generation Plant (eg Coal/Biomass)
