PMS 20 CONCENTRATION is a sensor module that uses the principle of laser scattering to detect the mass concentration of 4 channel particulate: PM1.0, PM2.5, PM10, TSP in the atmospheric environment. It could be either embedded in an instrument or use directly. The sensor is made with advanced processing chips and light-sensitive elements. After collected, the signals are processed by a microprocessor and output in the form of a universal digital interface.
The PMS 20 can accurately detect the mass concentration of different sizes of particles in the atmospheric environment in real-time.
