Ammonium/ Nitrate Sensor

The SMART ABAM – 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. The SMART ABNO – 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.
