Fluorescent DO sensors
The DO sensor was based on the principle of fluorescence quench to calculate the oxygen concentration via the inverse relationship between the time of the excited red light and the concentration of oxygen molecules, which can be used to detect the dissolved oxygen in water.
It is suitable for aquiculture, environment monitor, surface water station and many other water quality measurement scenes.
The sensor adopts self-developed fluorescent material, which has many features such as no oxygen consumption, maintenance free, long life, fast response and good anti-interference ability and stability.
