Product Description

Digital Infrared Turbidity Sensor

Digital turbidity sensor measures the cloudiness or haziness of a liquid, indicating the presence of suspended particles. It provides real-time data for water quality monitoring in various applications.

Features

OPTU300 series turbidity sensor uses 880nm infrared double beam

scattered light to measure turbidity. It is a multi-range, fast-response,

self-cleaning online suspended solids monitor. It is mainly used for

high-concentration sludge wastewater measurement.

Internal storage of calibration data, support offline calibration, plug

and play

Standard Modbus protocol, support access to standard industrial

control system

With cleaning brush for self-cleaning under water automatically
