Brand：Erun
Name：Online Ammonia Nitrogen Water Quality Monitor
Model：ERUN-SZ1S-A-E6
methodologies：Ammonia nitrogen (electrode method)
This product uses the ion-selective electrode method to measure ammonia nitrogen concentration. The ammonia ion-selective electrode directly detects ammonium ions in the aqueous environment to determine the concentration of ammonia nitrogen. The pH electrode is used as a reference electrode for better stability. Since the measurement result of the sensor is interfered by the dissolution of potassium ions, it is necessary to use potassium ion compensation when the concentration of potassium ions in water is high. Ammonia nitrogen sensor consists of ammonium ion selective electrode, potassium ion (optional), pH electrode, temperature electrode together to form a one-piece sensor, these parameters can correct each other's ammonia nitrogen measurement value, and at the same time to realize multi-parameter measurement.
