Introduction High concentrations of air dust not only endanger people's health, and even have a major safety hazard. For workplaces where the air dust concentration is high, the relevant management measures should be implemented, and the monitoring of dust concentration is the key link. SJFC-200B has many functions, such as continuous monitoring of particulate matter concentration, time sampling, and excessive dust concentration. The instrument has a built-in sheath gas protection gas path, which prevents the optical system from being polluted, with the function of self calibration, and is stable and reliable. SJFC-200 is widely used in factories, mines, construction sites and other places.
