GRIMM EDM 107 Hot-Spot Environmental Dust Monitor
Brand: Durag
The Grimm EDM107 dust monitor takes a continuous air sample with a flow controlled pump.
The particles are measured by the physical principle of orthogonal light scattering.
Here particles are illuminated by a laser light and the scattered signal from the particle passing through the laser beam is collected at approximately 90° by a mirror and transferred to a recipient diode.
Each signal of the diode is fed, after a corresponding reinforcement, to a pulse height analyzer then classified to size and transmitted in each size channel.
These counts are converted each 6 seconds to a mass distribution from which the different PM values derive.
