These small solid particles cause the liquid to appear turbid. Turbidity (or haze) is also applied to transparent solids such as glass or plastic. In plastic production haze is defined as the percentage of light that is deflected more than 2.5Â° from the incoming light direction.
The definition of Turbidity is the cloudiness or haziness of a fluid caused by suspended solids that are usually invisible to the naked eye. The measurement of Turbidity is an important test when trying to determine the quality of water.he most common measurement for turbidity in the United States are the Nephelometric Turbidity Units (NTU). There are several ways you can check turbidity in water, the most direct being a measure of attenuation, or reduction in strength, of a light source as it passes through a water sample.
