features

DYNAMIC OPACITY DUST MONITOR STACK602  
Mass concentration and light transmission can be measured simultaneously.
The monitor can perform black smoke detection during incomplete combustion and mass concentration measurement.
  • It is not affected by adhesion to the lens. (Adhesion up to 90% of the lens)
  • High concentration can be measured. (Resolution of 0.2 mg/m3)
  • A zero span self-diagnosing function is provided.
  • A 16-channel sensor is supported by the multi-controller (optional).
  • Most suitable for using in a large duct, boiler, incinerator, etc.

operating principles


The variation of light rays that pass over the duct is monitored and the ratio of the amount of light received and the variation (dynamic opacity) is calculated and detected.		 DYNAMIC OPACITY DUST MONITOR image
