Ammonia-Nitrate-Sensor

Introducing the SMART ABAM – Ammonia Sensor, a device designed to accurately measure the concentration of dissolved ammonia nitrogen (NH4’-N) in water. This advanced sensor utilizes three electrodes, including an Ammonia Ion Electrode, a Potassium Ion Electrode, and a pH Electrode, to precisely determine the NH4+-N concentration.

Similarly, we have the SMART ABNO – Nitrate Sensor, which effectively measures the concentration of dissolved nitrate nitrogen (NO3–N) in water. This sensor operates using two electrodes, namely a Nitrate Ion Electrode and a Chloride Ion Electrode, allowing for accurate determination of the NO3–N concentration.
