General Info

NDT James Instruments ‘Gecor 8™’ Advanced rebar represents the latest technology in steel reinforcing bar corrosion rate determination. It combines state of the art embedded microprocessor systems and computerized flash technology with the world’s leading research in reinforcing bar corrosion rate analysis.

The Gecor 8™ features:
• A method for rapidly mapping a structure’s corrosion rate. An advanced modulation confinement technique for precise corrosion rate analysis.
• A new corrosion rate analysis technique for use in very wet or submerged structures.
• New methodology for measurement of cathodic protection efficiency and more

The rapid mapping technique of the Gecor 8 allows the engineer to quickly classify areas of a structure while the unit’s built-in program can graphically analyze this data and produce contour maps of suspected areas. And, the advanced modulation confinement technique accurately measures the true polarisation resistance of the steel reinforcing bar.
