Overview

The RK500-04 Type-A Optical DO Probe is engineered for reliable and continuous monitoring of water quality in both natural and industrial environments. It combines dissolved oxygen and temperature sensing in a single compact device, providing real-time data with strong stability and fast response.

Built on fluorescence-based measurement principles, the sensor eliminates the need for oxygen-consuming chemical reactions, ensuring long-term accuracy and minimal maintenance requirements. It is resistant to flow variations and water ion interference, making it suitable for harsh and dynamic water conditions.

This probe is widely used in freshwater aquaculture, agricultural irrigation systems, rivers, channels, wastewater treatment plants, and environmental monitoring projects. Its robust IP68 protection rating allows for direct immersion or pipeline installation, ensuring dependable operation even in challenging field conditions.
