散射

According to the international standard ISO7027,we can know that the measurement of turbidity mainly use the optical turbidimeter measurement,it contains the scattering-light method and transmitted-light method. The scattering-light method has application in measurement for low turbidity water and also can used in high turbidity water.On the other hand,the transmitted-light method is more suitable for high turbidity measurement.
