A corrosion probe having in combination at least one first, at least one second, and at least one third electrode. A dielectric is positioned between the electrodes, and the dielectric has a structure defining an ionically conductive surface. An apparatus for measuring the corrosion rates of metals, or the like, in a corrosive liquid environment comprising the corrosion probe, a potentiostat electrically attached to the electrodes of the corrosion probe, and a signal generator electrically communicating with the potentiostat. The apparatus also has a voltmeter and an ammeter. A process for measuring the corrosion rates of metals in a corrosive liquid environment comprising attaching electrically the corrosion probe to a potentiostat. The corrosion probe is inserted into the corrosive liquid environment and either a predetermined known current is signaled to the potentiostat or a predetermined known difference in potential is signaled to the potentiostat. The potentiostat transmits the current, or applies the difference in potential, to the corrosion probe. An electromotive force between the first electrode and an area in the corrosive liquid environment in general microscopic proximity to the first electrode is determined. The corrosion current is computed from the determined electromotive force and the measured current. The probe may be utilized to detect electrochemically active components in a generally nonionic conductive fluid.
