    FAQ
    ❯

    The digital turbidity sensor operates based on the principle of 90° scattered light, calculating turbidity values by measuring the intensity of light scattered by suspended particles.

    ❯

    Possible causes include: the optical window being covered by dirt, the presence of air bubbles, lack of calibration, unstable power supply, or excessive water flow fluctuations.

    ❯

    It is recommended to install the sensor in an area with stable water flow and no air bubbles, or to use a mounting bracket with an anti-air bubble structure.

    Practical Solution for Water Quality Monitoring
    Our facility needed a simple way to monitor water clarity in a pilot treatment project. This digital turbidity sensor fit the range we were looking for and was reasonably easy to install. What stood out was the consistency of the measurements over time. We occasionally clean the probe as part of routine maintenance, and it quickly returns to normal operation afterward. It has helped us identify a few filtration issues earlier than we would have otherwise, which has been useful for day-to-day operation.
