EDM 264 - reliable and accurate dust monitoring all year round

Jan 04 2021 Read 805 Times

With the EDM264, GRIMM offers an 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 GRIMM‘s 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 GRIMM’s proven 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.  

GRIMM‘s EDM264 has 31 equidistant size channels, which are PSL traceable.

A high-end data logger enables data acquisition and wireless communication via LTE, WLAN 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.
