DMS-100 Dust Monitor (Extrctive)

Overview Of DMS-100 dust monitor (extrctive)

DMS-100 dust tester is a self-developed portable extraction dust monitor, which mainly adopts measuring technology oflaser forward scattering. The key parts of the product are all imported. The tester extracts dust in stack(flue) into dust measuring chamber for measurement. It owns features of high sensitivity, long maintenance-free time, convenient installation, which be can widely applied in ultra-low emission occasions.

Principle Of DMS-100 dust monitor (extrctive)


Under negative pressure effect of jet pump, dust in stack will enter measuring module via sampling rod. It employs forward scattering dust monitor principle of laser to measure dust concentration.
It uses compressed air to purge measuring module for cleaning. After maintenance, user can conduct zeroing by injecting filtered air.
Adjust one-way throttle valve to fix the velocity of dust extraction for measurement.

Features Of DMS-100 dust monitor (extrctive)


  • DMS-100 dust monitors manufactured by continuous emission monitoring system suppliers like ZETIAN adopts laser forward scattering method to measure dust concentration; low detection limit
  • Employ compressed air to purge laser and detector len, clean flow path
  • Support double range switching
  • Portable design, convenient for installation
