Portable Optical Dissolved Oxygen Meter
This product is an intelligent dissolved oxygen (DO) analyzer distributed by our company.
The dissolved oxygen sensor adopts optical fluorescence technology to measure dissolved oxygen in water. Based on the fluorescence quenching principle, the decay time of the excited red light is inversely proportional to the oxygen concentration, allowing accurate calculation of dissolved oxygen levels.
This instrument is suitable for applications including aquaculture, environmental monitoring, and water quality monitoring in industrial processes.
