Water Turbidity Sensor Probe, 0~50/200 to 4000 NTU

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.
