Introduction
The KWS-960C online turbidity sensor is designed and manufactured based on the principle of scattered light turbidity measurement. When a beam of light is projected into a water sample, the light is scattered due to the turbidity substances in the water sample. The turbidity in the water sample is calculated by measuring the intensity of the scattered light in the direction perpendicular to the incident light and comparing it with the internal calibration value. The final value is output after linearization processing.
