Product Specification

RS485 Digital Universal Ammonium Analyzer NH4-N Controller 800g

Brief Description Of The NH4-N Analyzer 

• The amount of nitrogen compounds in the water can be used as an indicator of the degree of pollution of the water body by nitrogen-containing organic matter. Ammonia nitrogen in water refers to nitrogen in the form of free ammonia and ionic ammonia. When the content of ammonia nitrogen is high, it is toxic to fish and harms the human body to varying degrees. The source of ammonia nitrogen in water is mainly the product of the decomposition of nitrogenous organic matter in domestic sewage by the action of microorganisms, certain industrial wastewater, and farmland drainage. Therefore, the amount of ammonia nitrogen in water has an important impact on humans. The determination of various forms of nitrogen compounds in water helps to evaluate the degree of pollution and the degree of "self-purification" in water bodies. Therefore, the determination of ammonia nitrogen in water is of great significance;

Product Feature Of The NH4-N Analyzer

• This ammonium analyzer is equipped with RS485 Modbus RTU, RS485 Modbus RTU provides a stable and reliable communication solution suitable for industrial environments, enabling different types of equipment to communicate and control each other, which is beneficial to the integration and management of industrial automation systems.

  RS485 allows multiple devices to be connected to the same bus and perform data transmission and control through serial communication protocols, making the integration between devices simpler and more flexible.

  RS485 uses differential signal transmission, which can resist electromagnetic interference in industrial environments and ensure stable data transmission.

  RS485 can support relatively long communication distances, allowing devices to be distributed in distant locations while maintaining reliable communication.

  Modbus RTU is a widely used communication protocol. Its standardization allows devices from different manufacturers to communicate with each other, increasing the interoperability and compatibility of the devices.

• The housing protection grade of the ammonium analyzer is IP66, which can effectively isolate the pollution and corrosive gas from the external environment;

• Menu password can be set to facilitate user's data confidentiality;

• Clock and historical data recording function, which can record 14,000 historical data, and the recording interval can be set between 1 and 999 minutes;

• 128*64 large-screen LCD display, Chinese and English language display, rich content, to meet the different needs of users;

• DUC series ammonium analyzers can meet a variety of installation methods, such as wall-mounted installation, pipe clamp installation, panel installation, and provide accessories required for installation.
