(1) A replaceable particle cutter is designed to realize the compatibility of PM10, PM5, PM2.5, TSP multiple particle separation cutters.

(2) An online filter membrane sampler is designed to realize continuous monitoring of dust concentration and compatibility with filter membrane sampling. It can analyze the collected particulate matter composition and calculate the mass concentration conversion coefficient K value of the site.

(3) Using laser light source, the mass concentration conversion coefficient is not affected by the color of particles.

(4) The instrument can directly measure the mass concentration value (mg/m3) that meets the WS/T206-2001 standard of the Ministry of Health.

(5) The large-screen LCD Chinese character display is adopted to realize the Chinese character menu prompt.

(6) A constant current controller is designed to ensure constant sampling flow and correct cutting curve

(7) It has a built-in optical standard bulk plate to ensure the high stability of the instrument.

(8) It has a special protective air curtain to avoid the pollution of dust to the core component of the instrument—the optical system, and ensure the high reliability of the instrument. The data obtained can be recorded by a micro printer or imported into a PC for data processing. This function is suitable for continuous monitoring of inhalable particles in the atmospheric environment.

(9) The alarm threshold for dust concentration exceeding the standard can be set, and the buzzer will automatically alarm when the dust exceeds the standard

(10) In addition to the general measurement mode suitable for dust monitoring in indoor public places and the regular sampling mode suitable for atmospheric environment monitoring, a new labor hygiene mode has been added.
