An optical instrument designed to measure the concentration of dust or particulate matter suspended in the exhaust gas passing through a duct, stack, or flue; typically the exhaust gas from an industrial combustion process or air filtration system.
Dust Analyzer uses the Innovative Dynamic Detection Principle (DDP) which measures fluctuations in the intensity of a light beam, using a folded beam Transceiver /Reflector arrangement. Increased particulate density in the stack causes the scattered light intensity to increase. When calibrated against reference standards, the intensity of this signal relates directly to the particulate concentration in the stack, and this can be used to display as a reading in mg/m³.
