Description

Anti-blocking dissolved oxygen tester

Technical Field

The utility model belongs to the technical field of dissolved oxygen meters, and particularly relates to an anti-blocking dissolved oxygen meter.

Background

Dissolved oxygen is used as a key index in aquaculture, plays a vital role in the growth and survival of fish, and seriously affects the life activities of fish. For example: the water dissolved oxygen content required by the normal growth and development of the fish is above 4-5 mg/L. Therefore, when the dissolved oxygen in water is lower than 2mg/L, the fish basically stops feeding, when the dissolved oxygen is lower than about 1mg/L, the fish can float, and when the dissolved oxygen is further reduced to 0.5mg/L, the fish can die by choking. Therefore, in aquaculture, the dissolved oxygen content of the water body of the fishpond needs to be monitored in real time through an dissolved oxygen meter so as to avoid the phenomenon of too low dissolved oxygen content of the water body, thereby reducing economic loss.

At present, along with the development of modern sensor technology, various dissolved oxygen sensors appear, and after oxygen molecules in a water body enter a probe (namely an dissolved oxygen electrode) of the dissolved oxygen sensor through a semipermeable membrane, the dissolved oxygen sensor can realize real-time detection of dissolved oxygen in water by utilizing an electrochemical principle.

However, various phytoplankton and algae exist due to the complex structure of materials in the aquatic culture water. The existing dissolved oxygen electrode head is often attached by organisms or impurities such as suspended matters or sediment in water after a period of use, and the attachments often cause the blockage of the dissolved oxygen electrode, so that the detection of the dissolved oxygen is inaccurate.
