Patent ID: 7238263

Claim:
A meter for marine corrosion testing, comprising: means for providing input from a reference electrode disposed in non-contact association with a component to be protected from corrosion; means for selecting the type of reference electrode; means for automatically calibrating data interpretation based upon the selection of reference electrode; means for selecting the type of metal being protected from corrosion; means for automatically calibrating data interpretation based upon the selection of the metal being protected; means to check proper completeness of electrical circuit between the metal being protected, the electrolyte, and the reference electrode; means to check power supply adequacy; means to monitor a waveform generated by a specific interrupted impressed current cathodic protection source; means to measure the potential of the metal being protected when the current generated by the impressed current cathodic protection source is temporarily interrupted; means to provide digital formatted display of magnitude of the potential being measured by the meter; means to provide electrical power supply to operate the meter; and means to house meter components.
