◆ The instrument adopts advanced β - ray absorption weighing + DHS (dynamic heating system) principle to directly measure the mass concentration of particulate matter It is not affected by the characteristics of particulate matter and does not need to be corrected. It can provide accurate data in real time all day long;
◆ It has the function of dynamic temperature and humidity compensation, which can ensure the accurate measurement of semi volatile nitrate and organic matter;
◆ Low activity C14 β source is adopted, which is safe and reliable (the company has radiation safety license);
◆ The flow control part of the instrument adopts frequency converter to control the regulating valve, which can accurately control the cutter when the outdoor temperature is - 30 ℃ ~ 60 ℃ The inlet flow rate was stable at 16.7l/min;
◆ Different cutters can be selected for real-time measurement of PM 10 and PM 2.5 concentrations;
◆ The PM 10 and PM 2.5 cutters are certified by China Center for Disease Control and prevention Inspection report issued by the prevention and control center for environmental and health related product safety;
◆ It adopts 7-inch high-definition LCD touch screen with Chinese display. One key start means the operation is completed without setting;
◆ It has the function of environmental temperature, humidity and atmospheric pressure measurement, and can automatically calculate the sample volume under standard conditions;
◆ The instrument can automatically store historical data, once every hour, and support sub data export;
◆ The built-in GPRS communication module can realize mobile phone app query and provide environment quality query service platform;
◆ It has digital output interface and can be connected with data acquisition instrument for network transmission;
◆ It has the functions of automatic diagnosis, remote alarm and automatic protection for filter paper and mechanical fault;
◆ The instrument can be equipped with wind direction and wind speed monitoring system, GPS positioning, noise monitoring system and video monitoring system.
