Product Specification

HYDRA NH4-N Ammonium Analyzer Description
The HYDRA^® Ammonium Analyzer measures the concentration of dissolved ammonium as nitrogen (NH4⁺-N) in water. The sensor uses three electrodes to determine the NH4⁺-N concentration, an Ammonium Ion Electrode, a Potassium Ion Electrode and a pH Electrode. It is designed for use in all kinds of water. Typical applications include monitoring environmental waters, lakes, streams and wells as well as wastewater treatment in aeration basins and effluent.

The Ammonium Ion Electrode provides the primary measurement. Any potassium ion in the sample generates a positive interference in the measurement, due to its similar size and charge to the ammonium ion. A Potassium Ion Electrode measures the amount of potassium ion present in the sample and HYDRA C22 Analyzer subtracts the appropriate amount of signal from the Ammonium Measurement.
