The calibration strategy using time-integrated samplers and rainfall events are complementary to each other and enable a correct calibration of turbidimeters and calibration tests regarding the effect of interfering factors (size, color and mineralogy).
Turbidimeter calibration with samples of suspended sediment representing the location is important because the spectral responses obtained by turbidity sensors have no universal connection with the SSC (Mylvaganam & Jakobsen, 2001).
Development of smaller, cheaper and easier to use turbidimeters will continue.
In this article it was shown how an integrated circuit of amplified photodiode might speed up development of turbidimeter.
If the turbidimeter
is not operating, the filter must be taken out of service which would cause reduction in capacity.

A mechanical stirrer and a turbidimeter
are also desirable.
Until recently, turbidimeters
were the sole measurement method used to maintain these standards.
The ratio turbidimeters
were used for pilot-plant process performanc evaluation because the calibration procedures for these instruments were carrie out more frequently.
