The DURAG D-R 290 has been used successfully for more than 15 years in various applications as reliable and low maintenance opacity / dust monitor. Now in its 2nd generation, the D-R 290 is a certified optical transmission monitor to measure the opacity or dust concentration of flue gases with medium to high dust concentrations.
The D-R 290 uses the double-pass method according to the auto-collimation principle. The light beam traverses the measuring path twice. The attenuation of the light beam by the dust content in the measuring section is measured and evaluated.
