PMS-200 Automatic Atmospheric PM Analyzer uses the principle of β ray absorption. The advanced microprocessor control unit can continuously and automatically monitor the concentration of PM2.5 or PM10 particles in the atmosphere. The product is mainly composed of a particle cutting head, an intelligent heating device, β ray source, a counting unit, a paper feeding control unit, an air extraction unit, an embedded computer, and a data display.
