The HYDRA DS Ammonium Sensor is designed to monitor the nutrient load (NH4+) directly in the aeration basin of a Wastewater Treatment Plant. The HYDRA uses ISE technology to measure the ammonium, potassium and pH. Compensation for the pH dependent NH4/NH3 concentration equilibrium and potassium ion interference on the ammonium electrode are performed automatically in the HYDRA T80 analyzer.
