Product Introduction

The KH.SZ-ZS Turbidity Sensor is a high-precision water quality monitoring instrument based on the light scattering principle. The sensor emits a light beam into the water sample, and suspended particles scatter the light. The detector positioned at 90 degrees to the incident light captures the scattered light, which is then converted to turbidity values through photoelectric conversion, signal processing, and software calculation. The sensor delivers real-time, stable turbidity measurements and supports RS-485 Modbus RTU output for easy integration with PLC, DCS, SCADA, or other industrial monitoring systems.

Key Features
