ISE Online Ammonia Nitrogen Sensor for Industrial Wastewater

Product description

Ammonia nitrogen is one of the most common water quality pollutants in the aquaculture industry. It mainly comes from the decomposition process of organic matter such as animal manure and feed residue in the aquaculture wastewater. If the content of ammonia nitrogen exceeds the limit of environmental tolerance, it will have a serious impact on the growth, reproduction, immunity, etc. of aquatic organisms, and even cause the death of fish. In addition, ammonia nitrogen will also affect the chemical properties of the water body, making the water body more acidic, thereby affecting the ecological balance of the water body. The NH351 online ammonia sensor developed and produced by daruifuno can monitor the ammonia nitrogen value of water quality online in real time, and the communication with RS485 can realize the output of data. The NH4-N sensor is easy to be attached by impurities in the water when it is used underwater for a long time. This ammonia sensor has a self-cleaning wiper to realize automatic cleaning under water. It can be used with our DUC2-NH ammonia controller to make more control functions.

Features of ammonia Sensor

● Use ISE(ion electrode ) measurement method;
● Realize online real-time monitoring, without adding any reagents during the detection process, and no secondary pollution;
● Automatically compensates for potassium ions (optional), pH and temperature in the water body;
● RS485 digital interface, standard Modbus protocol, support access to industrial control system and ammonia controller;
● The ammonia nitrate sensor has excellent repeatability and stability, and is not easily affected by ambient light；
● With self-cleaning brush to prevent biological attachment andreduce the frequency of maintenance.
