Brief introduction: WN - 6 - c inhalable particle analyzer labor industry standard of the light scattering measurement of dust concentration in the air, the ministry of health standards, the public determination method of inhalable particles (PM10) in the air - light scattering method. Detector outside air into the attraction, the labyrinth cutter to remove rough particles, covering the external light, into the detector dark room. Darkroom in the parallel light with the light of the vision into rectangular cross (slash) constitute the sensitive area, dust through the sensitive area, the direction of 90 ℃ scattered light through a slit in photomultiplier converts photocurrent, the photocurrent integral circuit converts and scattering light is proportional to the number of pulses per unit time. The number of pulses so records per unit time can be the relative quality of dust concentration. Technical indicators: The detection sensitivity: 1 CPM = 0.01 mg/M3; Determination principle: the principle of laser light scattering Microcomputer touch screen Measuring range: 0.01 ~ 100 mg/M3; Ambient temperature: - 5 ~ 40 ℃ Measurement accuracy: + / - 10% (relative correction particles) Data: data can store 200 level, Interface: microcomputer touch screen, K value and the correction coefficient, Output: connected to the PC, can print output Power source: 12 v rechargeable batteries, can use continuously for 12 hours,
