The GEO-RDM-642 Model operates using advanced forward light scatter laser Nephelometry.

It is particularly suitable when high precision is required in the measurement of the concentration of microparticles dispersed in the environment, as well as their classification according to their size.

Normally, the particle meter is connected directly to the METEODATA-4000 datalogger, which stores the data and transmits it to a Central Receiving Station.

The datalogger can also be connected to several additional sensors to measure other weather parameters that are of interest, creating a complete, autonomous field station for environmental monitoring, which can also be configured to form measurement networks.
