D-R 290 Optical Dust Monitor

Certified optical density analyzer for measurement of opacity and dust concentration in gas. It is used in process plants where dust emission control is required by law.

  • Applicable in systems with variable gas velocity
  • Allows calibration to measure dust concentration in mg/m3
  • Measures opacity and/or optical density
  • Can be used even in thick-walled masonry / insulated chimneys
  • The instrument is not in contact with the sample gas
  • Auto zero and datum check
  • Automatic measurement and correction for contamination of optical windows
  • Super Wide Bandwidth LED (SWBD), long life, reduced impact of variable particle sizes
  • Sealed enclosures - no flue gas intrusion into the optics or electronics
  • Optimized air purge reduces fouling, extends service intervals
  • Heated optical window
  • Easy to install, adjust and maintain, no PC required
  • Local control unit displays opacity, attenuation or mg/m3 values
  • Additional display unit optional for distance up to 1000m
  • Auto range output
