Continuous Particle Monitor

The GRIMM EDM 180 is the leading system for measuring particle concentration (PM10, PM2.5) in ambient air. This system offers simultaneous PM measurements in 31 channels with a particle size resolution of 0.1 μg/m3, and an isothermal inlet with Nafion membrane. Silent equipment that requires low maintenance and can be validated on site using the field test kit in conjunction with the system diagnostic software.
