Product Introduction

The KH.SZ-PHG Industrial Online pH Sensor is a high-precision digital measurement instrument designed for continuous monitoring of pH in industrial, environmental, and chemical process applications. Using advanced glass electrode technology combined with integrated microcontroller digital processing, it provides stable, accurate pH data with automatic temperature compensation.

With an IP68-rated waterproof design, the KH.SZ-PHG supports continuous submersion up to 60 meters, suitable for industrial tanks, reservoirs, wastewater systems, and chemical process control. Real-time pH readings are transmitted via RS485 Modbus RTU, enabling seamless integration with PLC, DCS, SCADA, and IoT monitoring platforms.
