DMS-100/MS-1000 Dust Monitor

HANGZHOU ZETIAN TECHNOLOGY CO., LTD was established in 2008, and as a fast-
growing company specialized in environmental pollution monitoring and
industrial process control, ZETIAN’s instruments and emission analyzers can
provide you best solutions.

Overview Of DMS-100/MS-1000
DMS-100/MS-1000 is a self-developed online dust analysis product and a dust
particle measuring device, adopting laser backward scattering measuring
technology with imported core components. The DMS-100/MS-1000 dust particle
measuring device is mainly used for continuous monitoring of PM emission
concentrations of various pollution sources. The DMS-100/MS-1000 dust particle
measuring device can be not only matched with CEMS continuous emission
monitoring system but also be used separately or together with multiple dust
monitors to form a dust monitoring network, sharing the same data collection
and processing background.

The DMS-100/MS-1000 dust particle measuring device is widely applied in
enterprises including thermal power, ferrous metallurgy, petrochemical
industry, cement production, potting, waste incineration; flue gas emission
monitoring in all kinds of power generating boiler, industrial kiln, and
industrial boiler; monitoring and control in gas desulphurization and dust
removal process.

Principle Of DMS-100/MS-1000 Dust Monitor
The dms 100/MS-1000 dust particle measuring device consists of the optical
part, circuit and signal processing part, calibrator and air curtain protection
part.

The laser beam (650nm) emitted by semiconductor laser enters the stack and
produces scattering light by interaction with dust particles. The backscattered
light of the DMS-100/MS-1000 dust particle measuring device enters the
photosensitive detector through the convergence of the lens. The signal
processing circuit converts the light signal into a standard signal in
proportion to dust concentration and output, thus dust particle emission
concentration of pollution source is obtained.
