Dissolved oxygen meter manufacturer

Dissolved oxygen meter, I believe that you in front of the screen, whether you are doing projects, engineering or planning yourself, are familiar with this term. As one of the important parameters of water quality, dissolved oxygen has a unique position in water quality products, and it is also one of the indispensable measurement parameters. So when we choose the manufacturer of the dissolved oxygen meter, how do we choose the manufacturer of the dissolved oxygen meter? Today, the editor will give you a simple answer to this question.　　 Before getting to know the manufacturer of the 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. The content of dissolved oxygen in the water is closely related to the partial pressure of oxygen in the air and the temperature of the water. Under natural conditions, the oxygen content in the air does not change much, so the water temperature is the main factor. The lower the water temperature, the higher the dissolved oxygen content in the water. The molecular oxygen dissolved in water is called dissolved oxygen, usually recorded as DO, expressed in milligrams of oxygen per liter of water. 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 original state, which indicates that the water body has strong self-purification ability, or that the water body pollution is not serious. Otherwise, it means that the water body is seriously polluted, the self-purification ability is weak, or even the self-purification ability is lost. Therefore, it is not difficult to see why dissolved oxygen is a water quality parameter that various industries need to monitor, and its significance is obvious. The dissolved oxygen meter is an instrument used to measure the content of oxygen dissolved in an aqueous solution. It can be used to measure the oxygen content that affects the reaction speed, process efficiency, or environmental process monitoring: such as aquaculture, biological reactions, Environmental testing (lake, stream, ocean), water/wastewater treatment, wine production and other technological links. On-line dissolved oxygen meters commonly used in industry can be broadly divided into two types. One is the earliest history of membrane method. It uses electrochemical principles. Currently, it has the largest number on the market and the cheapest price. Basically, industry giants are also involved. . The other kind of fluorescence method is the second generation technology of dissolved oxygen, which adopts the principle of fluorescence quenching, without polarization, and has a wider range of applications, but the price is higher, which will be about 3-5 times that of the ordinary membrane method. Therefore, we must pay attention to what kind of dissolved oxygen meter we should choose when we actually use it. From the perspective of imports, high-end brands such as E+H, Hash, and Mettler are the mainstream. Whether it is membrane method or fluorescence method, the technical level is far beyond the domestic technical level. Therefore, if the project budget is high, At the same time, if the requirements for professionalism and product performance are strong, these three imported companies are a good choice. At the same time, these three companies are also strong in water quality. Therefore, if it is a sewage treatment project, these three companies can provide good The one-stop service for you to select all the water quality instruments for the entire project. However, due to its nature, Mettler itself is more laboratory-oriented. If you want to use imported products, you may wish to give priority to Hash and E+H. If you use the laboratory type, Mettler is of course not yours. Two choices.　　 From the perspective of domestic production, there are many joint ventures in Beijing, and the prices are generally lower than imported but higher than domestically produced. The possible prices in other provinces are not much different. Kaidi is a manufacturer integrating five major industrial parameters. Its product coverage model similar to E+H is gradually being accepted by most manufacturers, and its fluorescent caps are completely imported from Hash. Expensive manufacturer.
