Online Turbidity Sensor

Product Introduction:

The turbidity sensor uses the principle of 90° scattered light detection, featuring advantages such as large measurement range, self-cleaning, and maintenance-free operation. It can be applied to turbidity measurement of backwash water in filter tanks at water treatment plants, measurements of turbidity in raw water and effluent from sedimentation tanks; monitoring water quality during industrial production processes; as well as routine water quality monitoring of surface water, groundwater, and pipeline networks.

Product Features:

Self-cleaning window coating reduces microbial contamination;

Designed with a self-cleaning wiper for secondary cleaning of the window surface;

The LED emits 880 nm near-infrared light, which compensates for sample color interference;

Continuous measurement with fast response, suitable for continuous monitoring and control;

Large measurement range with multiple selectable ranges to meet accuracy requirements for different applications;

Flexible installation methods, simple and easy to implement.
