Fish pond dissolved oxygen meter

There are many water quality parameters in our daily life that we need to monitor. Whether it is an industrial site or a living environment, water quality testing is an indispensable part, and dissolved oxygen is one of the more important requirements of many water quality parameters. Parameters detected. Speaking of dissolved oxygen, it is often used in sewage plants in industry, and everyone who is close to life must know that the aquaculture of fish ponds requires the control of dissolved oxygen parameters.　　 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 relying on the detection of instruments. The following mainly describes the use of science and technology and the use of water quality testing equipment (PH meter and dissolved oxygen meter) to rationally conduct aquaculture. The problem. And take everyone to understand how to choose the dissolved oxygen meter for fish ponds. First of all, we must know that different fish species have different developmental levels, growth cycles and health levels in water environments with different pH values. It may even be the consequence of inability to survive. Then the pH value must be strictly based on different types. The fish went to be monitored. The conventional traditional method is nothing more than sampling and testing with litmus paper, but in fact, the water quality parameters are ever-changing, and it is impossible to strictly monitor water quality by relying on litmus paper alone. Therefore, an online PH meter is needed to monitor the pH of fish ponds. value. The same is true for dissolved oxygen. Excessive or too small dissolved oxygen values u200bu200bin water are not conducive to fish pond breeding. Therefore, dissolved oxygen is also a parameter that needs to be controlled with an online dissolved oxygen meter.　　 Dissolved oxygen is closely related to the partial pressure of oxygen in the air, atmospheric pressure, water temperature and water quality. At 20°C and 100kPa, the dissolved oxygen in pure water is approximately 9mg/L. Some organic compounds undergo biodegradation under the action of aerobic bacteria, which consumes dissolved oxygen in the water. If organic matter is calculated by carbon, according to C+O2u003dCO2, it can be known that every 12g of carbon consumes 32g of oxygen. 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 further drops to 0.5mg/L, it can suffocate and die; while high dissolved oxygen generally has no harm to fish, too high dissolved oxygen is prone to air bubble disease. Dissolved oxygen in the water will be constantly replenished due to the dissolution of oxygen in the air and the photosynthesis of green aquatic plants. But 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, we need to use an online dissolved oxygen meter to help us monitor the dissolved oxygen in the water. Generally speaking, the dissolved oxygen meter is divided into membrane method and fluorescence method. The follow-up maintenance of the fluorescence method is small, the accuracy is better, but the cost is higher, relatively speaking, it is more suitable for the more important links in the industry or the links that are difficult to maintain. , And for fish ponds, the membrane dissolved oxygen meter is fully competent. Kaidi is a manufacturer covering the five major industrial parameters. Its dissolved oxygen meter also has a higher cost performance in the domestic market, and it is docked by one-to-one engineers to provide you with one-stop service.
