Y505-A Optical Dissolved Oxygen Sensor and Probe for Aquaculture
Dissolved oxygen in water refers to the molecular oxygen that is present in the liquid phase. It is essential for the survival of aquatic organisms and plants. Dissolved oxygen in water provides the oxygen necessary for the life activities of aquatic organisms. So, monitoring the concentration of dissolved oxygen in water is crucial for aquaculture.
Yosemitech Y505-A Optical Dissolved Oxygen Sensor and Probes designed specifically for aquaculture, adopting fluorescent materials independently developed by our self. No need for oxygen consumption, flow rate restrictions, electrolytes, maintenance, or calibration. This dissolved oxygen meter demonstrates outstanding resistance to interference and stability. It has a built-in temperature sensor, automatic temperature compensation.

FAQs
1. What role does dissolved oxygen play in aquaculture?
1. Providing necessary oxygen for the life activities of farmed aquatic organisms.
2. Promoting the growth and reproduction of aerobic microorganisms to facilitate the decomposition of organic matter and eliminate organic pollution in water bodies.
3. Directly oxidizing the more toxic H2S and NO2- in water into sulfates and nitrates, thereby reducing the toxicity of such substances.
4. Inhibiting the fermentation behavior of anaerobic microorganisms, creating a suitable breeding environment.
5. Enhancing the immunity of farmed aquatic organisms.
