SM-202M

Smoke Opacity Monitor for monitoring marine emissions

With Port Authorities around the world increasingly regulating emissions from ships, the SM-202M Smoke Opacity Monitor is an optical instrument specifically designed to measure the visible opacity of smoke emissions within the marine industry.

SM-202M

The SM-202M 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. This reduction in intensity is measured and presented as % opacity. The higher the level of smoke present, the more light lost and therefore, the greater the opacity.

Opacity

Opacity

Dynoptic opacity monitors use the light transmission technique to measure the visible opacity of exhaust gas in a duct, stack or flue.

Particulate

PArticulate

Particulate monitoring requires the measurement of the mass concentration of particulate matter in stack emissions to atmosphere.

Dust

Dust

Dynoptic dust monitors use DDP (optical scintillation which measures the dynamic fluctuation in light transmission as dust particles move through a light beam.
