CN0428 Water Quality Measurement System

ADI's CN0428 circuit shown is a modular sensing platform that allows the user to design a flexible electrochemical water quality measurement solution. Its high level of integration enables an electrochemical measurement platform applicable to a variety of water quality probes, including pH, oxidation reduction potential (ORP), and conductivity cells.

Many important liquid analyses like pH rely on electrochemistry, a branch of chemistry that characterizes the behavior of reduction-oxidation (redox) reactions by measuring the transfer of electrons from one reactant to another. Electrochemical techniques can be used directly or indirectly to detect several important parameters affecting water quality, including chemical indicators, biological and bacteriological indicators, and even some low-level contaminants like heavy metals. Many of these indicative measurements are pertinent to determining important quality parameters of the tested analyte.
