Optical Opacity/Dust Monitor

Durag Group develops and distributes products for industrial combustions and environmental monitoring. The company offers an Optical Opacity/Dust Monitor, D-R290. This is a standard system for plants with small to medium dust concentrations. Features: in-situ measuring procedure; continuous measurement; semi-conductor source with long service life; super-wide band diode (SWBD), which provides more stable measuring results in comparison to devices with conventional LEDs; powerful microprocessor technology; measured value display on LC display in opacity; extinction or in mg/m3; automatic function tests with correction of measured values in relation to soiling; optics and electronics in a hermetically sealed unit – no smoke gas can enter device; easy adjustment without additional equipment; and low-maintenance thanks to optimal purge air conduction. Applications: plants in which the dust concentration quantity needs to be measured, e.g., furnace plants with semi-anthracite coal, brown coal, fuel oil and combined heating; converter plants; asphalt mixing plants; and plants for cement manufacture. Approvals: suitability-tested by the TÜV Cologne, test report 936/801017, itemised in the list of suitable measuring devices for continuous emission measuring, MCERTS.
