- AOPLTU700 Low-Range Turbidity Analyzer
I. Measurement Principle
The instrument’s light source emits a collimated beam that enters the sensor perpendicularly, illuminating the water sample to be measured. Suspended particles in the sample scatter the light; the scattered light, which forms a 90° angle with the incident beam, is detected by a silicon photodiode assembly immersed in the water. The device calculates the relationship between the intensity of the 90° scattered light and the incident beam, thereby determining the turbidity of the water.
II. Main Features
The sensor supports continuous, uninterrupted data acquisition.
The measurement data are stable, and the measurement repeatability is excellent.
Equipment cleaning and routine maintenance are simple to perform.
Calibration modes supported: sample calibration and slope calibration.
The sensor is easy to install on-site, supports plug-and-play operation, and offers high deployment efficiency.
Digital sensing design with strong electromagnetic interference resistance and stable long-distance signal transmission.
Standard digital signal output is included as standard, enabling seamless system integration and networking with third-party devices without the need for a dedicated controller.
Accompanying display instrument: equipped with a backlit, all‑Chinese LCD screen;
Instrument mounting options include panel-mount and wall-mount configurations.
All‑Chinese operation menu; parameter settings and equipment commissioning are simple and easy to understand.
III. Application Scenarios
It is suitable for online turbidity monitoring of raw water, filtered water, and finished water at municipal water treatment plants, as well as in direct‑drinking‑water distribution networks. It can also be used for real-time, online turbidity measurement in industrial circulating cooling water systems, filtered effluent, reclaimed‑water reuse processes, and other similar operational stages.
IV. Technical Parameters
