Technical Description:

The sensor operates based on the combined infrared absorption and light scattering method. Infrared light emitted by the light source is scattered by suspended particles in the sample. This scattered light is then converted into an electrical signal by a photodetector. The signal undergoes both analog and digital processing to determine the sample's turbidity or suspended solids (SS) concentration value.

Technical Features:

• Digital turbidity sensor with strong anti-interference capability and long transmission distance.

• Allows for quick and easy sensor installation and replacement.

• Utilizes a dual-beam infrared scattered light detection technology, which eliminates interference from sample color.

• Offers excellent repeatability and stability.

• Integrated self-diagnostics function ensures data accuracy.

• Optional automatic cleaning brush accessory significantly reduces sensor maintenance requirements.

• High protection rating of IP68.
