Dissolved oxygen sensor in aquaculture


Aquatic organisms need oxygen in the water to sustain their activities. Oxygen in water is also called dissolved oxygen, and dissolved oxygen is one of the essential factors for aquaculture. Dissolved oxygen sensor can detect its concentration.

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.

dissolved oxygen sensor

In the process of aquaculture, the dissolved oxygen content in water is low due to climate change or abrupt change of water quality.

At this point, 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。nd the use of science and technology for intelligent aquaculture is becoming the mainstream trend.

JXCT has introduced a fluorescence method of dissolved oxygen sensor. The water sensor, based on fluorescence measurement principle, provides real-time monitoring of dissolved oxygen concentration signals for each aquaculture pond.

It 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:

Dissolved oxygen sensor mainly uses fluorescence quenching principle. Blue light shining on the fluorescent material causes the fluorescent material to excite and emit red light, because oxygen molecules can carry away energy (quenching effect).

So 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.
