DNH Ammonia Nitrogen Analyzer (ISE Method)
The ion-selective electrode (ISE) is a sensor designed to selectively respond to specific ions in a solution. The ammonia nitrogen ISE consists of a measuring electrode and a reference electrode. By selectively adsorbing ammonia ions, the sensor generates a corresponding potential difference, enabling rapid and accurate measurement of ammonia nitrogen concentration.
Product Application
● Online ammonia nitrogen monitoring in biological tanks of wastewater treatment plants
● Monitoring in pipeline networks, rivers, lakes, seawater, and aquaculture environments

DNH电极法氨氮分析仪是为测量市政污水或地表水中氨氮浓度而设计的在线分析仪表。为污水处理工艺调整或地表水水质监测和整治提供依据。
DNH电极法氨氮分析仪能自动补偿温度、PH和钾离子对氨氮测量带来的干扰。变送器和传感器之间的双向数字通讯可防止信号衰减，并允许传感器距离变送器之间的距离较远。传感器可选配空气清洗功能，能根据变送器预先设置的时间自动定时清洗，从而大大降低了仪器维护的工作量。
