Seawater Optical Dissolved Oxygen Probe for Fish Farming

Dissolved oxygen is one of the important elements of aquaculture, it is a substance formed by a variety of factors. From the perspective of fish energy conversion, after eating the bait in the water, after digestion, the energy in the food is converted into the energy needed for its own growth, and it can be used to grow up, in which oxygen plays a great role in the process of energy conversion. If there is not enough dissolved oxygen in the water, energy conversion will be halted and fish will grow slowly. In addition, in the case of sufficient oxygen in the pond, the bait and excreted feces in the water body will be decomposed into soluble organic matter by microorganisms, and then converted into inorganic matter through the water cycle, so that too much organic matter can be avoided and harmful gases can be produced to pollute the environment. Therefore, oxygen is an indispensable part of the process of organic transformation. Daruifuno's OPD700 Dissolved Oxygen Probe is specially designed for the aquaculture industry, which can be used not only in fresh water but also in seawater. The Dissolved Oxygen Sensor can be used separately or connect to our Dissolved Oxygen Controller to output the data.

FAQ

1. Does this optical dissolved oxygen sensor need to be maintain frequently？

A: Unlike electrochemical dissolved oxygen probe technology, fluorescent dissolved oxygen probes do not consume oxygen and do not require frequent cleaning (except when used in viscous liquids).

A: The fluorescent cap can be used for one year. You just need to replace it.
