portable digital turbidity meter
Introduction
The portable turbidity meter combines the scattered light method and the transmitted light method, and uses a near-infrared light source to eliminate chromaticity interference. Two detectors, 90°and 180°, are set in the instrument.The 180°detector receives the transmitted light and the 90°detector receives the scattered light. Measure the ratio of the intensity of scattered light and transmitted light, and calculate the concentration of suspended solids and turbidity in the sample.

Turbidity, the turbidity degree of water, is caused by the presence of trace insoluble suspended substances, colloidal substances in water. The measurement unit used in ISO standard is FTU (turbidity unit), which is consistent with NTU (turbidity measurement unit).
