Product Details
Aquaculture Fluorescence Dissolved Oxygen Sensor KWS-630 IP68
Introduction
The Aquaculture Fluorescence Dissolved Oxygen Sensor KWS-630 with
an IP68 rating is a game-changer in the aquaculture industry. It's
specifically engineered to meet the demanding needs of fish farms
and aquatic environments. This sensor utilizes fluorescence
technology to provide highly accurate and real-time measurements of
dissolved oxygen levels. The IP68 enclosure makes it fully
waterproof and dustproof, allowing it to operate flawlessly even
when submerged deep in water or exposed to harsh outdoor
conditions. Its compact and robust design enables easy installation
and maintenance, ensuring continuous and reliable monitoring of
oxygen levels to support the healthy growth of aquatic organisms.
Whether in freshwater or saltwater ponds, it's an essential tool
for aquaculturists.

The role of the fluorescence dissolved oxygen sensor in
aquaculture:
- Nutrient-rich feed and a good breeding environment are very
important in aquaculture. Of course, dissolved oxygen is also the
key to the survival of fish. During the breeding process, the
amount of dissolved oxygen in the water is high, and the water
quality and environment will become fertile and vitality, higher
feed utilization, increased fish food intake, and fatter growth.
- The function of Fluorescence dissolved oxygen sensor is to measure
the oxygen content in the water. The oxygen in the water will
change with the pressure, temperature and salinity. The higher the
pressure, the higher the dissolved oxygen, and the higher the
temperature, the higher the salt. Generally, the oxygen in the
water is air Infiltration into the water, it can also generate
oxygen through the plants in the water, but many reasons in the
water will consume oxygen, resulting in insufficient oxygen content
in the water, so professional instruments are required to detect
the dissolved oxygen content in the water.
- On the contrary, the dissolved oxygen in the water is low, the food
intake of the fish and the utilization rate of the feed will
decrease. At present, aquaculture is generally manually controlled
by manual aerators, which can effectively solve the problem of
aeration in water, but it is still inaccurate. The measured
dissolved oxygen content will lead to the occurrence of hypoxia,
which will cause great damage to aquaculture.
- It can intelligently control the aerator. When the oxygen content
is low during the breeding process, it can automatically control
the oxygen machine to increase the oxygen. When it reaches a
certain oxygen content, it will automatically disconnect. It brings
a lot of convenience in breeding and reduces the Labour and
increases aquaculture production.
