Forward Scattering Dust Monitor QAL181

 

    ►Features  
This monitor can make stable detections regardless of the presence or absence and types of dust chambers and exhaust gas treatment systems including a large boiler and large kiln.
  • The pin spot measurement minimizes the influence of various conditions.
  • High resolution: 0.1 mg/m3 Recommended measuring range: 0 to 10/100 mg/m3
  • A zero span self-diagnosing function is provided.
  • A 16-channel sensor is supported by the multi-controller (optional).

      ►Operating Principles 
Laser light is irradiated on dust particles, and the scattered light (forward light scattering method) is collected and scattered by the mirror, and then detected through the quartz rod. As forward-scattered light from which the largest scattering intensity can be obtained is collected with an efficient collection mirror and detected through the quartz rod without transmission loss, the monitor can make stable detections with less influence of noise.
