    Overview

    Water turbidity sensor probe employs the 90° scattering light method and supports RS485 (ModBus-RTU) communication. It enables continuous and accurate monitoring of water turbidity, with selectable measurement ranges of 0~50/200/1000/4000 NTU and a resolution up to 0.1 NTU. SUCH turbidity sensor has a response time of approximately 30 seconds and is suitable for various scenarios including agricultural water use, industrial discharge, mine wastewater, aquaculture, surface water monitoring, and end-of-pipe treatment of domestic sewage. It operates stably in environments ranging from 0~50℃ and <0.6MPa.

    Feature

    • Fast response and stable measurement using laser scattering, unaffected by magnetic interference for continuous monitoring.
    • Supports online detection with simultaneous measurement of turbidity and temperature in one device.
    • Fiber-optic structure with a built-in temperature sensor minimizes external light interference, offering high sensitivity and long service life.
    • High protection performance with IP68 rating, allowing use underwater up to 20 meters.
    • Built-in temperature sensor provides automatic temperature compensation to reduce errors and improve accuracy.
    • Equipped with a 3/4 NPT tapered thread for easier installation and secure mounting.

    It uses the 90° scattered light method. When a light beam enters the water sample, suspended particles cause the light to scatter. The sensor measures the scattered light intensity at a 90° angle to the incident beam and compares it with internal calibration values. After linear processing, it calculates and outputs the final turbidity value.

    ❯

    1. It is recommended to clean the sensor probe every 30 days to remove any attached substances.

    2. Avoid using hard objects during cleaning to prevent scratching the probe’s optical surfaces.

    3. Wipe gently with a soft, damp cloth.

    ❯

    It is ideal for agricultural water, industrial wastewater, aquaculture, surface water monitoring, and sewage treatment.

    Perfect water turbidity sensor probe, keeping my fish tank clean
    Picked up this water turbidity sensor probe for my recirculating aquaculture tanks because the water was getting muddy way too fast. Dropped it straight into the filtration sump line. The 90 degree scattering method catches the floating waste particles instantly. No more guessing when to flush the mechanical filters, really helps a lot.
