An economical method for identifying areas of corrosion.
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 is a measurement 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.
To analyze the results, the measurements made with CorMap® can be plotted on a grid and lines of equipotential contours drawn, highlighting areas of possible corrosion activity.
Easy to use.
Detachable electrode extension pieces facilitate measurements in hard to reach locations.
High impedance digital meter is designed for tough field conditions.
Electrode is designed for use on horizontal, vertical and inverted positions.
Economical.
