Product Tag - potential detector

Concrete resistivity tester is also called potential detector. The corrosion of steel bar/ reinforcement in concrete is an electrochemical process, it creates an electric current to make metal dissociation. The lower the resistivity, the easier corrosion current flowing through the concrete, and the greater the likelihood of corrosion. So measuring the resistivity of concrete can effectively evaluate its ability to resist corrosion and evaluate existing steel corrosion degree.
