SJFC-200 Dust Monitor is used to monitor the mass concentration of the suspended particulate in the air. It adopts light scattering technique and has sheath air protecting. It is applied to work place measurements, mines and construction site air quality control, occupational studies, ambient air measurement, ventilation filter control (filter efficiency).

Using three channels (PM1.0, PM2.5, PM10.0) to measure and display the results at the same time, this method fully complies with the relevant national laws, regulations and standards. Due to the automatic measurement method, errors caused by manual operation can be effectively avoided, frequent calibration and zero adjustment are not required, and work efficiency is effectively improved. 

Features: 

Built-in sheath gas protection gas circuit to prevent the optical system from being polluted 

With the self-calibration function, the measurement is stable and reliable
