DSL-230M

Smoke Density Monitor for monitoring marine emissions

With Port Authorities around the world increasingly regulating emissions from ships, the DSL-230M Smoke Density Monitor is an optical instrument specifically designed to measure the concentration of smoke and particulate emissions within the marine industry.

DSL-230M

The DSL-230M 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 smoke 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 smoke density and present a reading in mg/m³.
