Single Pass Particle Monitor for monitoring particulate and smoke emissions
The DSL-230 Particulate Monitor is an optical instrument designed to measure the concentration of dust or particulate matter in an exhaust gas passing through a duct, stack or flue.
The DSL-230 uses the single pass light transmission measurement technique, with Transmitter/Receiver arrangement. A light beam emitted from the Transmitter passes across the stack to a Receiver, which measures the intensity of the received light.
Increased particulate density in the stack gas attenuates the transmitted light and causes the intensity of the received light to fall. When calibrated against standard reference measurements, this reduction in intensity can be used to calculate the particulate concentration and present a reading in mg/m³.
