Importance of fluorescence dissolved oxygen sensor for aquaculture

Dissolved oxygen sensor can be widely used in water treatment, aquaculture, biological reaction and many other fields.

Background:


Oxygen is one of the basic conditions for human existence on earth. Similarly, aquatic organisms need oxygen in the water to sustain their activities. In aquaculture, oxygen in water is also known as dissolved oxygen, dissolved oxygen is one of the essential factors of aquaculture.


When dissolved oxygen content in water is sufficient, organic matter can be decomposed quickly under the action of aerobic bacteria. After decomposition, the product is CO2 and other substances harmless to aquaculture organisms.


When the dissolved oxygen content in water is insufficient, the bacterial reproduction in water layer is dominant, and the decomposition products are mostly toxic substances to animals in water.


Therefore, it is necessary to maintain sufficient dissolved oxygen in the water to inhibit the chemical reaction of toxic substances, and only sufficient water dissolved oxygen can ensure the normal growth of aquaculture fish, shrimp and so on.


Application:


In the process of aquaculture, due to climate change or sudden changes in water quality, the dissolved oxygen content in water is low. At this time, it is necessary to add oxygen to the aquaculture water.


In the past, aquaculture was all a matter of experience. The staff can only adjust through their own intuition, if the adjustment is not accurate, it will affect the growth of animals in the water.


Nowadays, the aquaculture industry is in the stage of transformation and upgrading, and the use of science and technology for intelligent aquaculture is becoming the mainstream trend.


JXCT has introduced a fluorescence method of dissolved oxygen sensor. Based on the principle of fluorescence method, this water sensor can monitor the dissolved oxygen concentration signal of each aquaculture pond in real time, which is scientific, accurate, and time-saving.

It is convenient for the aquaculture personnel to know the water quality of the pond in real time and take corresponding measures in time to achieve the effect of intelligent breeding. Dissolved oxygen sensor can be widely used in water treatment, aquaculture, biological reaction, environmental monitoring, laboratory, medical and many other fields.


Product Introduction:


The fluorescence method of dissolved oxygen sensor mainly uses the fluorescence quenching principle. Blue light illuminates the fluorescent material to excite it and emit red light. Since oxygen molecules can carry away energy (quenching effect), the time and intensity of the excited red light is inversely proportional to the concentration of oxygen molecules. The oxygen concentration can be calculated by measuring the phase difference between the excited red light and the reference light and comparing with the internal calibration value.
