RS485 Ammonium Analyzer NH4 - N Digital Universal Water Quality Transmitter

Brief Description Of The NH4-N Analyzer

1. Water pollution will seriously restrict the rapid development of the economy and society. As one of the main pollution factors of water pollution, ammonia nitrogen mainly comes from domestic sewage, coking wastewater, farmland drainage, synthetic ammonia fertilizer plant wastewater, and aquaculture water. Because the ammonia-containing organic matter is affected by microorganisms, a large amount of waste will be generated. In addition to the excess feed and a large amount of excrement for fish, shrimp, etc., when people irrigate the farmland, excessive fertilization will seriously affect the ammonia nitrogen content in the water quality. The analysis of the ammonia nitrogen content in the water body can determine the degree of water pollution and control the water quality in the best state, which is of great significance to environmental governance.

2. The DUC2-NH4-H-A is a single parameter controller, each controller, will be pre-installed with a set of embedded software to adapt to different NH4-N digital sensors.

3. Two high-precision 0/4~20mA current outputs with a maximum load of 1000 ohms;

4. Two settable SPST multifunctional relays with a maximum load of 3A/250V AC;

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

6. The water quality transmitter has a two-wire RS485 interface, the communication protocol is MODBUS RTU, and supports JSON text data format;

7. The shell material of the NH4-N analyzer is enhanced ABS, its overall size is 144*144*120mm;

8. Its operating environment of the ammonium nitrogen analyzer is 0~60℃, relative humidity is less than 95% (non-condensing); its storage environment is -20~70℃, relative humidity is less than 55% (non-condensing).
