Description
Overview
GAOTek 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.
