GRIMM EDM180 is an environmental particle monitor/aerosol particle size spectrometer which is certified by many countries. Based on the laser scattering principle, the mass concentration of PM 10 and PM 2.5 in the ambient air can be obtained at the same time. The system has excellent functions and can measure PM simultaneously in 31 particle size channels with a resolution of 0.1 μg/m3. The equipment does not require consumables and can automatically prompt for possible error states and required maintenance. Therefore, the reliability of the system is greatly improved, and it is a solution to realize reliable environmental monitoring.
