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.
Advantages of optical dissolved oxygen measurement
• Easy use, no membrane, no electrolyte.
• Long lifetime, maintenance free and less calibration.
• No flow dependency and fast response.
• Immune to electrical interference, no chemical interference.
