Suzhou Fluorescence Dissolved Oxygen Analyzer

The fluorescence method dissolved oxygen analyzer uses fluorescence to measure dissolved oxygen. The top of the sensor is covered with a layer of fluorescent substance. When the blue light emitted by the sensor shines on the fluorescent substance, it is excited to emit red light. Due to the quenching effect of oxygen molecules, the time and intensity of the excited red light are inversely proportional to the concentration of oxygen molecules. The concentration of dissolved oxygen in water can be calculated.

Product model: SS-DO-01

　　Fluorescence dissolved oxygen analyzerApplication environment:

Industrial and municipal sewage treatment plants: regulating tanks, aeration tanks, aerobic/anaerobic digestion tanks, and effluent detection, etc;

Water environment monitoring, rivers, lakes, seawater, fishing grounds, etc.

Testing method:

Dissolved oxygen is measured using fluorescence method. The top of the sensor is covered with a layer of fluorescent substance. When the blue light emitted by the sensor shines on the fluorescent substance, it is excited and emits red light. Due to the quenching effect of oxygen molecules, the time and intensity of the excited red light are inversely proportional to the concentration of oxygen molecules. By calculating, the concentration of dissolved oxygen in water can be obtained
