Fish pond dissolved oxygen meter detector

In daily life, water quality parameters are closely related to our lives. Whether it is an industrial site or the immediate environment, water quality is a topic that all of us need to detect and care about. Dissolved oxygen is such an important water quality parameter. There are many application conditions for dissolved oxygen, and the one that is closest to our lives, and also the most practical, is the detection of dissolved oxygen in fish ponds.　　Before understanding the fish pond dissolved oxygen meter, the editor will first popularize a concept for everyone, that is, dissolved oxygen. The molecular oxygen in the air dissolved in water is called dissolved oxygen. Dissolved oxygen value is a basis for studying the self-purification ability of water. The dissolved oxygen in the water is consumed, and it takes a short time to return to the initial state, indicating that the water body has strong self-purification ability, or that the water body pollution is not serious. Otherwise, it shows that the water body is seriously polluted, the self-purification ability is weak, or even the self-purification ability is lost, which is undoubtedly extremely unfavorable for breeding.　　 Looking at aquaculture from the perspective of water quality, anyone who has a little understanding of ring maintenance fish knows that the first thing related to fish is the problem of dissolved oxygen. Therefore, the colleagues in fish farming are not only concerned about common sense of life, but also rely on the detection results of the equipment, and use the water quality detection equipment to rationally conduct aquaculture. Different fish species have different levels of development, growth cycle, and health in different pH water environments, and it may even be the consequence of not being able to survive. When the dissolved oxygen value in the water drops to 5mg/L, some fish will have difficulty breathing. The dissolved oxygen required for the normal growth and development of the main farmed fishes is generally above 4~5mg/L. At this time, the fish eat well. , Rapid growth, high utilization rate of erbium; when the dissolved oxygen is lower than this value, the fish’s food intake and growth will be affected to a certain extent; when the dissolved oxygen is lower than about 2mg/L, the fish basically stop eating; when the dissolved oxygen When it drops to about 1mg/L, it will float; when the dissolved oxygen drops further to 0.5mg/L, it will suffocate and die. When the water body is polluted by organic matter, the oxygen consumption is serious, and the dissolved oxygen cannot be replenished in time, the anaerobic bacteria in the water body will quickly multiply, and the organic matter will turn black and smelly due to corruption. When the dissolved oxygen is not properly controlled, the water body will be polluted, and the fish will naturally not survive, so the follow-up work of aquaculture will not be discussed. Therefore, at this time, a sophisticated dissolved oxygen detector is required for real-time monitoring to avoid losses caused by various reasons.　　 Most of the pond culture in our country still relies on manual observation of fish and shrimp floating heads to open an aerator. There is a certain hysteresis, and the floating head phenomenon is unavoidable. Once the floating head starts, it indicates that the dissolved oxygen content of the pond has been too low. It is necessary to increase oxygen for rescue immediately. Although timely rescue can avoid large-scale flooding of the pond, it has adversely affected the normal growth of fish and the water quality of the pond. Therefore, it is necessary to use an online dissolved oxygen meter for real-time monitoring and monitoring through actual data. Conventional dissolved oxygen detector, the measuring range is generally 0-20mg/L, the membrane method (of course, economic conditions permit the use of fluorescence method) dissolved oxygen meter for measurement, and the measured signal is converted into a dissolved oxygen controller Acceptable signals, such as 4-20mA signal or RS485 communication, so that on the one hand, the dissolved oxygen can be detected by the on-site control equipment, and on the other hand, it can also be watched on the spot to monitor the breeding situation in real time.
