    Overview

    High-quality water turbidity sensors deliver high-precision measurements across ranges of 0–20 NTU, 0–100 NTU, and 0–1000 NTU, with a resolution as high as 0.01 NTU. The water quality sensor supports automatic temperature compensation (Pt1000), with RS485 (Modbus-RTU) output compatible for various monitoring systems. The IP68 protection rating ensures reliable long-term underwater operation.

    Feature

    Water quality turbidity sensor feature

    • The all-in-one turbidity sensor is designed and manufactured based on the 90° angle scattered light turbidity measurement principle.
    • Supporting RS485 (Modbus/RTU protocols), it is compatible with multi-system data output. The SUCH water quality turbidity sensor features a fiber-optic structure with strong resistance to external light interference.
    • Utilizing an infrared LED light source with IP68 protection rating, it delivers stable measurements at depths up to 20 meters.
    • When a light beam enters the water sample, turbidity particles cause light scattering. By measuring the intensity of scattered light perpendicular to the incident beam and comparing it to internal calibration values, the turbidity is calculated. The final value is output after linearization processing.

    FAQ
    ❯

    Turbidity sensors typically measure using either the scattered light method or the transmitted light method. When light hits suspended particles in water, it scatters or attenuates. The water turbidity sensor calculates the turbidity value by detecting changes in the light signal.

    ❯

    Most industrial turbidity sensors feature an IP68 protection rating, enabling long-term submersion. However, it is essential to ensure the cable is properly sealed and that the interface end remains dry. Additionally, appropriate maintenance based on the environment is required, such as regularly cleaning the probe to prevent algae or sediment buildup from affecting optical detection performance.

    ❯

    Turbidity sensors typically support water temperatures ranging from 0 to 50°C and can operate under certain pressures, such as up to 0.2MPa. If conditions exceed these ranges, it is recommended to use high-temperature or pressure-resistant models to prevent damage to the optical components.
