The ammonia nitrogen sensor uses an ion-selective electrode and has a membrane with a specific type of  ion permeability, The composite sensor composed of this selective membrane and electrolyte can be used to measure the redox potential of the required specific ions (for example, NH4+).

Application fields: sewage treatment plant treatment process and discharge port water quality monitoring, industrial process water quality monitoring, surface water/groundwater monitoring, other industrial wastewater treatment process and discharge port monitoring installations, etc.
