ABSTRACT:
A method of investigating corrosion includes providing a mounting unit for two or more electrical contacts, introducing the mounting unit to a replica of a location which has not corroded, measuring the voltage between the two or more electrical contacts at one or more times, the two or more electrical contacts being in contact with the replica of the location being investigated, introducing the mounting unit to the location which may have corroded, measuring the voltage between and/or the variation in the voltage between two or more electrical contacts at a first time and at one or more other times, the two or more electrical contacts being in contact with the location being investigated, passing a current through the replica location at the time of the voltage measurement and through the location at the time of the voltage measurements, the voltage measurements for the location indicating the extent of corrosion.
