dust monitor

Compact and cost effective transmittance dust and opacity measuring device for monitoring medium to high dust concentrations in dry flue and process gas.


  • Non-contact measuring method
  • Continuous measurement of opacity and dust concentration
  • Suitable for medium or high dust concentrations on short to medium measuring lengths
  • Automatic internal self-test, zero point and reference point check
  • Manual contamination and linearity check
  • Extremely low-maintenance due to self-test functions and LED source
  • Easy installation and commissioning with universal operating unit and adjustment tool
  • Convenient operation including remote access capability
  • Cost-effective, small measuring system
  • Operation with or without control unit


  • Easy set-up for opacity monitoring
    No gravimetric calibration needed when using transmission principle for reliable opacity monitoring
  • Compact and cost effective solution
    The smallest available DURAG dust monitor comes with an attractive system pricing
  • Broad functional range due to dual-path transmission principle
    The sensitivity scales up with growing duct diameter. This allows for measuring very low dust concentrations in very big stack diameters and vice versa very high dust concentrations in small stack diameters
  • Suitable for harsh flue gas conditions
    Non-contact measurement with purge air cushion technology allows for very high flue gas temperatures and aggressive flue gases
  • Designed for a wide range of environmental conditions
    Corrosion-free plastic housing and a broad ambient temperature range
  • Reliable emission monitoring
    Automatic control functions ensure reliable measuring values
