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



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



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