Ammonia Nitrogen Electrode innoSens 550


The innoSens 550 ammonia nitrogen electrode uses the ion-selective 

electrode method to measure the concentration of ammonia nitrogen in 

water. The ammonia ion-selective electrode is used to directly detect 

ammonium ions in the water environment to determine the 

concentration of ammonia nitrogen.
