Rebar Corrosion Voltmeter Kit
Caltech Engineering Services offer rebar corrosion voltmeter kit complete economical kit for identifying areas of rebar corrosion in concrete as per ASTM C-876.
Rebar corrosion voltmeter kit includes half-cell and voltmeter integrated with a high impedance and long earth cable and dispensing damp sponge. When rebar corrosion voltmeter DV-05 is connected between the reinforcing steel, Cu-CuSO4 reference half-cell electrode (Fontana-101F) and specially made highly electrical conductive dispensing sponge on the concrete surface where a measurement can be made for the half-cell potential. This gives 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
- Easy to use
- Detachable electrode extension pieces facilitate measurements in hard to reach locations - Optional
- High impedance digital meter is designed for tough field conditions
- Electrode is designed for use on horizontal, vertical and inverted positions
- Economical
- Conforms to ASTM C-876
Corrosion, which is an electrochemical process, occurs in concrete when oxygen and moisture are present. The actual corrosion is an exchange of energy within different sections of the uncoated reinforcing steel. The relative energy levels can be determined in relation to a reference electrode with a stable electrochemical potential
