The SC9400 Ammonium Sensor measures the concentration of dissolved ammonium as nitrogen (NH4+-N) in water. The sensor uses three electrodes to determine the NH4+-N concentration, an Ammonium Ion Electrode, a Potassium Ion Electrode and a pH Electrode. It is designed for use in all kinds of water. Typical applications include monitoring environmental waters, lakes, streams and wells as well as wastewater treatment in aeration basins and effluent.
