Half Cell Potential Measurement
PCTS measure the potential of an embedded reinforcing bar relative to a reference half-cell placed on the concrete surface. The concrete functions as an electrolyte and the risk of corrosion of the reinforcement in the immediate region of the test location is related empirically to the measued potential difference.
Introduction
CTS technicians are available to measure monitor and map concrete reinforcements potential for corrosion. This test can give the probability of corrosion activity taking place at the point where the measurements of potentials are taken from a half-cell, (typically a copper-copper sulphate half-cell).
Application
CTS Technicians are available to:
Produce isopotential contour maps
Identify corrosion risk
Monitor expected corrosion
