Opacity QAL1 Approved Particulate CEM  


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

Add to Compare
  • 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)
