The High Resistance Compensation Method (HRCM) was developed to measure the electrode potentials of high resistance electrodes. It is essentially similar to the classical Poggendorff compensation method, but instead of an ampere-meter, the pH-meter was introduced as an indicator of complete compensation. The method was applied to measurements of the electrode potentials of a single crystal rutile
(TiO2) electrode. Electrode potentials were converted to surface potentials, and the dependency of the surface potential on pH in aqueous medium was determined
