MODEL EDM264
The Highest Class Of Accuracy
Reliable and accurate dust monitoring all year round
The EDM264 is the optimal solution for both short- and long-term, mobile measurements in outdoor areas and at production sites.
The model EDM264 features a powerful and robust measuring cell based on optical particle counting (OPC) technology with all the advantages that users of our portable aerosol spectrometers are accustomed to.
The system is embedded in a compact, weatherproof housing equipped with a heated sampling inlet, sigma 2-head, a data logger and meteorological sensor.
The EDM264 provides all fine dust fractions for ambient air measurements: TSP, PM10, PM4, PM2.5, PM1, PMcoarse , calculated with the proven GRIMM enviro-algorithm, as well as six additional dust mass fractions: pm10, pm2.5, pm1, inhalable, thoracic and respirable for IAQ and workplace measurements.
This versatile instrument performs real-time monitoring of particle number and particle size and provides information on particle surface distribution and dust mass distribution.
The GRIMM EDM264 has 31 equidistant size channels, which are PSL traceable. A high-end data logger enables data acquisition and wireless communication via LTE, WIFI or wired via Ethernet. Backup copies of the measurement data are stored directly in the device.
The rinsing air function, which protects the illumination and detection optics in the optical cell, increases the reliability and long-term stability of the system. The entire sample volume flow of 1.2 L/min is analysed in the optical cell, providing excellent counting efficiency at low and high concentrations.
With all these features, the EDM264 is a world-leading instrument for precise monitoring of dust masses, particle surfaces and particle number concentrations.
This reliable instrument is an indispensable tool for users, who need to measure aerosol concentrations and air quality outdoors, on construction sites, or at production facilities.
