A localized corrosion monitoring (LCM) device is modified to obtain polarization resistance (Rp) from electrical resistance of a probe having a strip of metal under investigation (test electrode), a reference electrode and a temperature sensor (e.g. thermocouple). This configuration allows the probe to be used in areas where only a thin film of conductive fluid is available or required to provide potential monitoring. Thus, the applicability of the LCM technique is broadened. All the above devices are expected to be configured in one item of equipment, except for the probe which may be remotely located from the rest of the equipment. |
