Overview

The RK500-06 ORP sensor is engineered to deliver accurate and continuous monitoring of water quality parameters, specifically oxidation-reduction potential, which is critical for assessing chemical reactions in liquids. Built with a durable structure and platinum ring electrode, the sensor offers high sensitivity, fast response, and long-term operational stability. Its integrated signal isolation and strong anti-interference capability make it suitable for demanding industrial environments where electrical noise and harsh conditions are common.

This sensor supports both analog (4–20 mA) and digital (RS485) outputs, allowing seamless integration into various monitoring and control systems. The robust IP68-rated design enables long-term submersion in water without compromising performance. Additionally, its simple installation and maintenance process make it a practical solution for continuous water quality monitoring in applications such as sewage treatment, river monitoring, reservoirs, and industrial wastewater systems.
