DSL-240 MkIII

Single Pass Dust Monitor for monitoring dust emissions using DDP

The DSL-240 Dust Monitor is an optical instrument designed to measure the concentration of dust or particulate matter in the exhaust gas passing through a duct, stack or flue.

DSL-240 MkIII

The DSL-240 uses the innovative Dynamic Detection Principle (DDP) in which a light beam emitted from the Transmitter passes across the stack to the Receiver, which measures fluctuations in the intensity of the received light. Increased dust or particulate density in the stack causes the amplitude of these fluctuations to increase. When calibrated against standard reference measurements, the amplitude of this signal relates directly to the dust concentration in the stack and this can be presented as a reading in mg/m³.

Dynoptic 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.
