Overview
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. It is mainly used for continuous monitoring of PM emission concentrations of various pollution sources. It can be not only matched with CEMS 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.
Principle Of DMS-100/MS-1000 Dust Monitor
DMS-100/MS-1000 dust monitor 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 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.
Features Of DMS-100/MS-1000 Dust Monitor
•Support online zero and span calibration
•Automatic gain control function and temperature compensation
•Convenient for installation, disassembly and cleaning with small and compact structure
•Able to eliminate the influence of background stray light
