Joint Test - SIN-ADI3000 Industrial Ionic Composite Ammonia Nitrogen Electrode

The ammonia nitrogen electrode is based on the reaction principle of ammonia nitrogen competing for free electrons with hydrogen ions in water for measurement. At a specific pH value, ammonia nitrogen is replaced by hydrogen ions (H+) in water molecules, forming ammonium ions (NH 4+) and releasing an electron. When the ammonia nitrogen electrode is placed in the sample, its surface is coated with a special material called a membrane layer. This membrane layer can selectively allow ammonia nitrogen to pass through and react with electrode media on the electrode surface, generating a current signal. By measuring the magnitude of the current signal, the concentration of ammonia nitrogen in the sample can be calculated.
