ABSTRACT:
The invention is directed towards improved accuracy of investigations into corrosion using the methods and apparatus of the invention. In particular, the invention provides a method of investigating corrosion at a location, the method including measuring 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, passing a current through the location at the time of the voltage measurements, providing a power source external of the location to provide an applied current, using the respective voltage values from the two or more electrical contacts in the investigation of the corrosion, the part of the applied current passing through the location being measured by the use of the Hall effect.
