Product description
DMS-300 dust monitor is a self-developed high-temperature heat tracing extraction dust monitor, based on years of technology research and development for dust detection.

Adopt laser forward scattering method to detect dust concentration; low detection limit.
Full-process heat tracing
Pitot tube isokinetic sampling method meets the technical condition of dust sampling
Support automatic purging to clean gas path and avoid dust blocking
Support automatic zeroing technology under high temperature and automatic calibration technology of all optical paths
Support on-site manual span calibration
Support automatic double range switching
