Description

Product description
DMS-200 dust monitor is a self-developed probe-in monitor, based on years of research on dust detection technology. Different from traditional back scattering dust monitor (such as DMS-100/MS-1000), DMS-200 installs dust measurement module at the top of probe, which directly stretches into the stack for dust measurement in close distance and it adopts laser forward scattering method to realize low detection limit.

Features
Adopt laser forward scattering method to measure dust concentration; the lower detection limit is as low as 0.05mg/m3
Employ gas curtain purging to protect laser and lens of detector end; purging gas is automatically heated by the temperature of stack inside feeler lever and achieve positive pressure dust prevention inside feeler lever
High temperature resistance design of probe part
Automatic zeroing and calibration of double optical path
Support manual range calibration
Support automatic range calibration
