DSL-230 MkIII

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.

DSL-230 MkIII

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.

Product Applications

Below are our core product applications, simply select them for more information about suitable monitors

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.
