Overview

DMS-300 I dust monitor is a self-developed extraction dust monitor, based on years of technology research and development for dust monitoring. It uses laser forward scattering prnciple to monitor the dust concentration. It owns features of low detection limit(as low as 0.05mg/m3), no interference by moisture with full process high temperature heat tracing for measurment. It can be widely applied in stack emission, powder manufacturing and processing, and lab continuous monitoring etc.


Application for stack emission monitoring and process control such as coal-fired plants, waste incineration plant, cement, ceramics, deSOx, deNOx technology
