James Instruments, Inc. Cor-Map System
A simple economical method for identifying areas of probable rebar corrosion
Features & Benefits
An economical method for identifying areas of corrosion ASTM C-876.
A high impedance voltmeter is connected between the reinforcing steel and a Cu-CuSO4 reference electrode on the concrete surface where a measurement can be made for the half-cell potential.
This measurement is of the probability of corrosion activity. By testing at a fixed distance apart, a grid of half-cell potentials can be developed and areas delineated.
