Electrochemical measurements, including those taken using pH probes, Oxidation/Reduction Potential (ORP) probes, Ion Selective Electrodes (ISEs), and Electrolytic Conductance (EC) probes, primarily rely on potentiometry. In potentiometric measurements, the probe detects a potential in millivolts (mV), which can be directly reported as the measurement result (as with ORP), or used to calculate the final result through a calibration process (as with pH and ISE).
