Online dissolved oxygen meter manufacturers

Speaking of dissolved oxygen, everyone may be more unfamiliar than the relative pH and other parameters, but in fact, dissolved oxygen is a very important industrial parameter. Whether it is in industrial sites or in some breeding level tests, dissolved oxygen is not acceptable. An indispensable part. The online dissolved oxygen meter is an instrument that responds to the need for long-term testing and can provide feedback on the detected data. So who are the manufacturers of online dissolved oxygen meters? Today I will take you to learn about the manufacturers of online dissolved oxygen meters.　　Before getting to know the manufacturers of online dissolved oxygen meters, 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 initial state, indicating 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 the aqueous solution. From its portability, the dissolved oxygen meter can be divided into: portable dissolved oxygen meter, desktop dissolved oxygen meter and pen-type dissolved oxygen meter. And from the use can be divided into: laboratory dissolved oxygen meter, industrial online dissolved oxygen meter and so on. Therefore, before selecting a dissolved oxygen meter manufacturer, you must first clarify what kind of dissolved oxygen meter you need. The online dissolved oxygen meter is an instrument that is commonly used in various industrial sites. The online dissolved oxygen meter can be broadly divided into two different principles of online dissolved oxygen meter: membrane method and fluorescence method. Nowadays, most of the wastewater treatment plants use fluorescent dissolved oxygen meters. The membrane method has been gradually eliminated due to problems such as accuracy and post-maintenance. However, it is still suitable for some occasions due to its low cost. The membrane method has the earliest origin in history. 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. When it comes to manufacturers who produce dissolved oxygen meters, they have to mention that imported high-end brands such as E+H, Hach, and Mettler are the mainstream. Whether it is membrane method or fluorescence method, its technical level is far beyond domestic Technical level. Therefore, if the project budget is high, and the requirements for professionalism and product performance are strong, these three imported companies are a good choice. At the same time, the water quality of these three companies is also strong, so if it is For sewage treatment projects, these three companies can provide a good one-stop service to select all the water quality instruments for the entire project for you. And if you plan to replace it with domestic products, Kaidi is a company that focuses on process automation. Its product series are complete and can provide you with one-stop service. The fluorescent cap is completely imported from Hash, which is a cost-effective online dissolved oxygen. Instrument manufacturer.
