D-R 800 Scattered Light Dust Monitor
Brand: Durag
Scattered light dust monitor to measure small to medium dust emissions.
The D-R 800 works according to the principle of forward scattering.
The concentrated and modulated light of a laser diode penetrates the measuring volume.
The forward-scattered light largely reflected from dust particles is measured and assessed.
Features- Easy installation on one side of the duct
- Easy installation, no alignment needed
- Long lifetime as there are no moving parts inside the duct
- Probe with corrosion resistant nano-tech coating
- Automatic zero and reference point check
- Automatic contamination control and correction.
