Product Description

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& Advantage

1.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.

2.Internal storage of calibration data, support offline calibration, plug and play.

3.Standard Modbus protocol, support access to standard industrial control system.

4.With cleaning brush for self-cleaning under water automatically.
