Detail Durag D-R 290 Opacity & Dust Monitor

D-R 290 Opacity & Dust Monitor


  • Continuous and contactless measurement
  • Automatic zero and span check
  • Automatic measurement and correction of contamination of optical surfaces
  • Extremely powerful and stable super-wide band diode (SWBD) light source
  • Extremely low-maintenance
  • Fail-safe shutters with purge air monitoring as option
  • Certified according to EN 15267-3
  • Compliant with US-EPA 40 CFR 60 PS1, PS11, and ASTM D6216 - 12


  • Certified for official emission monitoring
    Type approved according to EN 15267-3, compliant with the requirements of US-EPA 40 CFR 60 PS1, PS11, and ASTM D6216 - 12
  • Easy set-up for opacity monitoring
    No gravimetric calibration needed when using transmission principle for reliable opacity monitoring
  • 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
  • Durable through options purge air monitoring and fail safe shutter
    Protection of the device through continuously monitored purge air supply and automatic closure of fail safe shutter in case of purge air failure
  • Rugged design for harsh environmental conditions
    Suitable for a wide range of application due to heavy duty metal housing, a broad ambient temperature range and optional versions for EX environments
  • Reliable emission monitoring
    Automatic control functions ensure reliable measuring values
