The AM7 Ammonium Sensor measures the concentration of dissolved ammonium 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.
The NO7 Nitrate Sensor measures the concentration of dissolved nitrate nitrogen (NO3--N) in water. The sensor uses two electrodes to determine the NO3--N concentration, a Nitrate Ion Electrode and a Chloride Ion 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.
