Low Range/High Precision Turbidity Meter | 0-20NTU

High Precision Portable Turbidity Meter Measures Total Suspended Solids from 0-20 NTU.

The portable turbidity/total suspended solids analyzer combines the scattered light and transmitted light methods, 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. The unit then measures the ratio of the intensity of scattered light and transmitted light, and calculates the concentration of suspended solids and turbidity in the sample.

Features a bright, high definition LCD full color display, and multi-power mode for battery and USB powered operation. The near-infrared LED light source is IS7027 compliant, and the unit offers IP65 protection suitable for field use. Built-in lens, filter and high precision optical path provides stable and accurate results
