Electro-Chemical Devices (ECD) products

The HYDRA Nitrate Sensor is designed to monitor the nitrification process directly in the aeration basin or clarifier of a Waste Water Treatment Plant. The HYDRA uses ISE technology to measure the Nitrate and Chloride. Compensation for the chloride ion interference on the nitrate electrode is preformed automatically in the HYDRA C22 analyzer. Also available with an optional pH sensor.

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.
