Suspended Particles in the air are sampled at3 constant sampling rate of 0.9 to 1.4 m /minthrough the inlet of cyclone. By virtue of theirmomentum , particle greater than 10 microns arecarried vertically upward by the air flow andcollected on a filter paper of 8 x 10 inch. Whilecoarse dust is collected in a cup placed under thecyclon.

The FLD-1 Real-time Dust Monitor is a measuring instrument with an optical scattering method particle monitor inside the cabinet, enabling it to continuously assess particles at outdoor locations. With this instrument, it is possible to monitor the particle concentration without changing the instrument configuration at outdoor locations. In addition, various output interfaces using multiple units of the instrument make it possible to measure the particle concentration at the fence lines of premises, or at construction sites.
