The probe and housing are integrated into a single unit, resulting in a simple and compact structure that is easy to use. It is designed for accurate measurement of turbidity in water, with a \u003cb\u003emeasurement range of 0-1000 NTU, a resolution of 0.1 NTU, and an accuracy of ±5% FS\u003c\/b\u003e. The water turbidity sensor uses an infrared LED light source and a fiber optic light path design, incorporating a filtering algorithm to provide strong resistance to external light interference.\u003c\/p\u003e\u003cp style=\"text-align: center; \"\u003e\u003cimg src=\"https:\/\/dfimg.dfrobot.com\/enshop\/image\/data\/SEN0710\/1.png\" alt=\"Overview of RS485 Industrial Water Quality Turbidity Sensor (0-1000 NTU)\" title=\"Overview of RS485 Industrial Water Quality Turbidity Sensor (0-1000 NTU)\"\u003e\u003c\/p\u003eThe turbidity sensor is equipped with an \u003cb\u003eRS485 communication interface\u003c\/b\u003e and supports the \u003cb\u003estandard ModBus-RTU protocol\u003c\/b\u003e.
