Sensor working principle
Fluorescence Method Dissolved Oxygen Analyzer is based on the "quenching" principle of certain substances to reactive fluorescent in the physics, which detects the concentration of dissolved oxygen or partial pressure of oxygen in the water.
The front-end measuring sensor consists of two LEDs (emitting red-ray and blue-ray separately), photoelectric detector and the fluorescent cap.
