Online ammonium ISE sensor measures ammonium electron concentration without using any chemicals. No reagent, no pollutants, more economic and environmentally friendly. The sensor uses pH, Ammonium Ion electrode, and reference electrode to determine the NH4+-N concentration. It is designed for use in all kind of natural water, such as lakes, streams, rivers, as well as wastewater plants.
