product key technologies
The dissolved oxygen (DO) electrode is a key sensor used to measure the concentration of dissolved oxygen in water. It is widely applied in wastewater treatment, aquaculture, environmental monitoring, laboratory research, and various industrial water process systems.
Adopting either polarographic or optical fluorescence measurement technology, the DO electrode features fast response, high stability, strong anti-interference ability, and low maintenance requirements. It is waterproof, corrosion-resistant, and supports multiple installation methods including immersion, flow-through, and pipeline mounting.
When used with a transmitter or multi-parameter water quality analyzer, it enables real-time and accurate monitoring of dissolved oxygen, helping users control water quality and optimize process operation efficiently.
