DynamicOpacity™ Dust Monitor


Stand alone Cross Stack optical dust monitor suitable for measuring emissions after electrostatic precipitators and stacks without filtration systems

  • Used for emissions measurement (mg/m³) after electrostatic precipitators and baghouses or Process control applications
  • Advanced sensor design includes automatic drift (zero and span) checks
    • Simple installation and maintenance
    • Resistant to contamination. Will work with optics 90% obscured
    • External display and keyboard for easy set up
    • Blowers not required can be purged with instrument air
    • Simple installation, set-up and maintenance
    • Resistant to contamination, operational with optics 90% contaminated
    • Lower levels of maintenance than traditional Opacity systems
    • Can be purged with instrument air providing lower cost of ownership; blowers available if preferred
    • mg/m³ output, once calibrated.
    • Stacks after Electrostatic precipitators, bag filters, cartridge filters, cyclones, or no filter
    • Non-condensing / dry flue gases
    • Variable flue gas velocities, including low velocity flue gase
      Typical applications:

    • Incineration
    • Metals e.g. Steel/Aluminium
    • Minerals e.g. Cement
    • Power e.g. Boilers/Biomass
