MODEL EDM164
A GENUINE NEAR-REFERENCE METHOD
Small & Compact PM Monitor for Continuous Outdoor Monitoring
The EDM 164, in its compact and mobile weather housing, performs reliable optical detection for counting and classifying dust particles. The EDM 164 is applicable for short and long-term continuous monitoring of dust pollution and enables a real-time data analysis of dust and meteorological measurement data.
This configuration places the EDM 164 in the leading position of the mobile environmental dust monitoring for such applications as dust mass, PM values, total counts and particle size distribution. The EDM 164 is the optimal solution for reliable environmental monitoring, e.g. PM monitoring, source identification, or pollution control at construction and mining sites.
Overview
