Transparency meters (SS meters) provide an important management
parameter for the water quality standards of discharged
water. The CST-200 transparency meter (SS meter) performs
continuous measurement of the transparency (suspended solid
concentration) of discharged water. This meter can be
effectively used for notification of water quality abnormalities
and for management of the operating conditions of wastewater
treatment facilities.

[Summary provided by COS]
A transparency meter, also called a clarity meter, is an instrument used to measure the transparency of an object. Transparency refers to the optical distinctness with which an object can be seen when viewed through plastic film/sheet, glass, etc. In the manufacture of sheeting/film, or glass the quantitative assessment of transparency is just as important as that of haze. Transparency depends upon the linearity of the passage of light rays through the material. Small deflections of the light, caused by scattering centers of the material, bring about a deterioration of the image. These deflections are much smaller than those registered in haze measurements. While haze measurements depend upon wide-angle scattering, clarity is determined by small-angle scattering. Wide and small angle scattering are not directly related to each other. By this, we mean that haze measurements cannot provide information about the clarity of the specimen and vice versa.
