When corrosion occurs the ferric oxide protective layer surrounding the concrete breaks down allowing an electrochemical reaction between the steel and the concrete.
In the half-cell test, a reference electrode is passed over the surface of the concrete and the potential voltage difference is recorded. These potential voltage readings show where corrosion is likely to be, or is currently present.
The Elcometer 331 Half-Cell Meter is available in two models - Model H and Model HM.
Elcometer 331 Model H: entry level gauge without memory which allows users to measure the half-cell potential in concrete structures.
Elcometer 331 Model HM: supplied with memory and allows users to store up to 240,000 readings in either linear or grid batches.
