The CORI-GPS lets you harness the power of Global Positioning System (GPS) technology anywhere in the world to conduct on-off corrosion surveys with unprecedented precision. This is the world's only fully programmable portable current interrupter using GPS technology for zero drift. The CORI-GPS allows you to program synchronized interruption cycles. With the CORI-GPS you can, for example, program the simultaneous interruption along a pipeline of several rectifiers connected to CORI-GPS units.Since each CORI-GPS obtains its synchronization signal via satellite, interruption can be performed with an accuracy of ±5 milliseconds. This means that you can perform close-interval surveys along a pipeline without the risk of obtaining “Instant OFF” readings which would be skewed by badly synchronized interruption.
The CORI-GPS obtains its timing information via satellite signals available free of charge world-wide. Since the satellite information received is based on Universal Coordinated Time it must be converted into a ‘Pipeline Time’ common to all current interruption units used in a particular survey.
