Opacity Approved Particulate CEM  

PCME STACK 710

QAL1 approved particulate CEM which meets US EPA PS-1 requirements for Opacity monitoring from combustion stacks

Robust multi corner cube reflector provides truer reflection of transmitted light compared to traditional “mirror type” reflectors providing greater confidence in measurement

  • Outstanding reliability with no continuously moving parts
  • Automatic in-situ zero and span checking with built-in calibration audit and zero drift correction
  • Dual light source, with patented Flood LED source provides robust check of the detectors
    and minimises effects of temperature instability
  • 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 Refinery / Rubber)
  • Power Generation Plant (eg Coal/Biomass)
