D-R 220 Optical Dust & Opacity Monitor
Brand: DuragThe D-R 220 operates using the double-pass method according to the auto-collimation principle.
The light beam emitted by the transceiver crosses the measuring path twice.
The attenuation of the light beam by the dust in the measuring section is detected and evaluated.
A long-life LED is used as a light source.
