    FAQ
    ❯

    Wash the outer surface of the sensor with tap water. If debris remains, wipe it with a damp, soft cloth. For stubborn dirt, add some household detergent to the tap water for cleaning.

    ❯

    The cable should not be taut during normal operation; otherwise, the internal wires may break, causing the sensor to malfunction.

    ❯

    It is suitable for water treatment, environmental monitoring, industrial process control, aquaculture, and general water quality assessment.

    optical turbidity sensor works as expected
    I use this optical turbidity sensor in my water monitoring setup. The installation process was simple, and the readings look consistent during normal use. The first few days I spent some time checking the data and cleaning the sensor, but that is expected with this type of product. Overall, it works well and does what I need.
