SDW016 Intelligent COD Sensor

Short Description:

SDW016 is an intelligent COD sensor based on deep ultraviolet (UVC) absorption method to measure organic matter in water and integrated optical path difference technology. It adopts RS485 communication interface and standard ModBus/RTU communication protocol.The sensor can quickly (in seconds) measure COD, BOD, TOC, turbidity, water temperature and other water quality parameters, real-time reflection of water body changes.

The sensor has the ability of variable optical path and the unique optical path difference function, which not only greatly expands the range, but also eliminates the impact of window pollution, which greatly increases the accuracy and reliability of measurement.

Functional Characteristics

1. UVC&VIS dual wavelength technology, effectively eliminate the influence of turbidity and chromaticity.

2. With highly integrated optical design, dual wavelength beam coaxial output, beam sampling optical path is.

3. Realized and light intensity monitoring sensor is set.

4. The original optical path difference measurement technology, through the mechanical process of variable optical path and the calculation process of optical path difference algorithm, can effectively eliminate the interference caused by residual attachments of the cleaning brush, window scratches and wear, etc.

5. Automatic cleaning brush and optical path difference technology can achieve true maintenance free.

6. Corrosion resistant housing, IP68, long-term underwater operation.
