Product Introduction

The KH.SZ-DDM Online EC Sensor is a high-precision digital conductivity sensor designed for continuous water conductivity monitoring in rivers, lakes, reservoirs, and freshwater environmental monitoring systems.

Using advanced electrolytic conductivity measurement technology combined with intelligent digital processing, the sensor provides stable and accurate electrical conductivity (EC) data with automatic temperature compensation.

The IP68 waterproof design enables reliable long-term deployment in outdoor water environments, while RS485 Modbus RTU communication allows seamless integration with telemetry systems, SCADA platforms, and IoT-based smart water monitoring networks.

The KH.SZ-DDM is widely used for:

• River water quality monitoring
• Reservoir and lake observation
• Hydrological monitoring stations
• Environmental water assessment
• Smart water management systems
• IoT water quality monitoring platforms

By providing continuous conductivity data, the sensor helps users analyze water conditions, support ecological studies, and improve water resource management.

How It Works

The KH.SZ-DDM measures electrical conductivity by detecting the ability of water to conduct electrical current.

The sensor processes conductivity signals through integrated digital electronics and applies automatic temperature compensation to maintain measurement accuracy under different water temperature conditions.
