Product Introduction

The KH.SZ-ZS Optical Turbidity Sensor is a high-precision online water quality monitoring device designed for continuous turbidity measurement in environmental, industrial, and aquatic applications.

Based on optical light scattering technology, the sensor detects suspended particles in water by measuring scattered light intensity and converting optical signals into accurate real-time turbidity values.

The KH.SZ-ZS provides stable turbidity monitoring in various water environments, including:

• Rivers and streams
• Lakes and reservoirs
• Wastewater treatment systems
• Aquaculture facilities
• Industrial process water systems
• Smart water monitoring networks

With an IP68-rated submersible design supporting long-term underwater deployment, the sensor delivers reliable performance with reduced maintenance requirements.

RS485 Modbus RTU communication enables seamless integration with:

• PLC systems
• DCS platforms
• SCADA systems
• IoT water quality monitoring platforms

The KH.SZ-ZS helps users achieve continuous water quality assessment, environmental protection, industrial process control, and smart water management.

How It Works

The KH.SZ-ZS uses optical light scattering measurement technology.

A light source emits a beam into the water sample. Suspended particles scatter the light, and a detector positioned at a specific angle measures the scattered intensity.

The internal processing system converts the optical signal into turbidity values.

This measurement principle provides:

• Real-time turbidity monitoring
• Accurate suspended solids detection
• Stable performance in complex water conditions
• Long-term continuous operation
