Description

TECHNICAL FIELD

[0002] The fluorescence method dissolved oxygen analyzer is an instrument for measuring the dissolved oxygen concentration in water by using the fluorescence measurement principle. Its working principle is based on the "quenching" effect of active fluorescence of specific substances. The front end of the measurement sensor is composed of two light-emitting diodes (emitting red light and blue light respectively), a photodetector and a fluorescence cap. The fluorescence substance at the front end of the fluorescence cap is a special ruthenium metal compound. The fluorescence substance is coated below the polyester foil that allows gas molecules to pass through. A layer of black light-blocking material is coated on the upper surface of the polyester foil to avoid the interference of sunlight and other fluorescent substances in water.
