DSL-240 MkIII - Single Pass Dust Monitor - Brochure

The DSL-240 is an optical instrument designed to measure the concentration of dust or particulate matter in the exhaust gas passing through a duct, stack, or flue; typically the exhaust gas from an industrial combustion process or air filtration system. The DSL-240 uses the innovative Dynamic Detection Principle (DDP) in which a light beam emitted from the Transmitter passes across the stack to the Receiver, which measures fluctuations in the intensity of the received light. Increased particulate density in the stack causes the amplitude of these fluctuations to increase. When calibrated against standard reference measurements, the amplitude of this signal relates directly to the particulate concentration in the stack, and this can be presented as a reading in mg/m³.
