LM 3086 SER Dust and Opacity monitor



  • Reliable, robust laser technology
  • Easy installation
  • Reduced maintenance
  • Unique simulated Zero and Span Calibration system
  • Continuous control of the optical surfaces
  • TÜV Approval acc. to 13. BlmSchV and TA Luft
  • MCERTS Performance Standard version 4, dated July 2018: EN15267 and QAL1
  • Approval against Russian GOST standard


  • Dirt in optics is eliminated from the measurement values, providing real long-term accuracy and stability
  • Automatic calibration and zero check 40 times per second


  • Measuring path up to 20 meters without changing a single component in the system
  • Excellent beam collimation (narrow and intense laser light beam)
  • Standard wavelength together with optical reference path guarantees long term accuracy and stability


  • Start-up diagnostic for basic system health check
  • Continuous diagnostics in background for alerting exceptions  or out of specification situation
  • Multiple display alternatives for optical and mass readings
  • Easy to integrate with CEMS systems
  • Onsite auditing without dismounting in installation location
