1. Product information
Ammonia nitrogen sensor includes 4 sensors: temperature, pH, ammonia nitrogen, potassium ion. A wide range of physical, biological and chemical properties of natural water bodies can be monitored.
The concentration of ammonia nitrogen was measured by ion selective electrode method. The ammonium ion selective electrode directly detects the ammonium ion in the water environment to determine the concentration of ammonia nitrogen. The pH electrode is used as the reference electrode to obtain better stability. In the process of measurement, the concentration of ammonia nitrogen is easily interfered by potassium ion, so potassium ion compensation is needed.
Ammonia nitrogen sensor by ammonium ion selection electrode, potassium ion (optional), pH electrode, temperature electrode together to form an integrated sensor, these parameters can modify each other, compensate the measurement value of ammonia nitrogen, while realizing multi-parameter measurement.
It is widely used in nitrification treatment of sewage treatment plant, aeration tank, industrial engineering and ammonia nitrogen value of river water.
