Embodiments relate generally to systems and methods for identifying the concentration of an electrolyte. A method may comprise scanning a working electrode of an electrochemical sensor using cyclic voltammetry at a plurality of electrolyte concentrations; generating a variable set of readings from the first cyclic voltammetry scan using a potential difference between a hydrogen adsorption peak and a Pt-Oxide reduction peak at each of the plurality of electrolyte concentrations; and determining a correlation by plotting the variable set of readings and the plurality of electrolyte concentrations. In some embodiments, the method may comprise scanning a working electrode of a second electrochemical sensor using cyclic voltammetry, wherein the second electrochemical sensor has been employed; generating a second set of readings; and determining the electrolyte concentration of the electrolyte of the second electrochemical sensor by applying the determined correlation to the second set of readings.
