Ammonia Analyzer, Ammonium Analyzer for WWTW Applications

A sample of gas is then taken from the headspace, passed through the sensor and the response analyzed to provide a concentration in ppm of the ammonia in the water (Fig. 2). What does the MS3500 Ammonia Analyzer actually measure? The MS3500 measures the concentration ammoniacal nitrogen in wastewater, as given by the sum of NH3 and NH4
