Our Inline Optical Dissolved Oxygen Sensor sensor uses advanced fluorescence technology for dissolved oxygen measurement.

The sensor operates by emitting blue light onto a phosphor layer, exciting a fluorescent material that emits red light. The duration for the fluorescence to return to its ground state is inversely proportional to the oxygen concentration, enabling precise measurement without oxygen consumption. This method provides stable, reliable, and interference-free data, with simple installation and calibration.

This sensor is widely used for continuous dissolved oxygen monitoring in sewage treatment processes, water plants, surface water, industrial process water, wastewater treatment, aquaculture and more.

Key Features:

• Equipped with a new oxygen-sensitive film for exceptional reproducibility and stability
• Innovative fluorescence technology requires minimal maintenance.
• Customizable maintenance reminders, triggered automatically.
• Durable, fully enclosed design enhances sensor longevity.
• Simple and reliable operation with intuitive interface instructions, minimizing errors.
• Visual warning system offers essential alarm functions.
• Convenient on-site installation with plug-and-play capability.
