RS485 Output Ammonia Nitrogen Meter for Sewage Water Treatment
Product description
Ammonia nitrogen in water refers to ammonia in the form of free ammonia, which mainly comes from decomposition products of nitrogen-containing organic matter in domestic sewage by microorganisms, industrial wastewater such as coking synthetic ammonia, and farmland drainage. When the content of ammonia nitrogen in water is high, it is toxic to fish and harmful to human beings in varying degrees. The determination of ammonia nitrogen content in water is helpful to evaluate the pollution and self-purification of water, so ammonia nitrogen is an important indicator of water pollution.
The DG-NHNG-3010 online and automatic ammonia nitrogen meter/analyzer can work automatically and continuously for a long time without attendance according to the site settings. It is widely used in industrial pollution source discharge wastewater, municipal sewage treatment plant wastewater, environmental quality surface water and other occasions. According to the complexity of site test conditions, the corresponding pretreatment system can be selected to ensure the test process is reliable,test results are accurate, and fully meet the needs of different occasions.
