SJFC-200 Dust Monitor

Brief introduction

The instrument has a built-in sheath gas protection gas path, which can effectively prevent the optical system from being polluted, so it can be used to test the high dust concentration in the condition of bad working conditions. Combined with communication technology and software technology, real-time monitoring system can be built. The system has many functions, such as continuous monitoring of particulate matter concentration, time sampling and dust concentration (early warning), and other functions, such as temperature, humidity, combustible gas concentration, O2 concentration, CO2 concentration, CO concentration, wind speed, wind direction, noise, etc.. Monitoring system can be applied to factories and mines (dust monitoring), construction sites
