Specification :

Concrete Resistivity apparatus is also called potential detector ( corrosion analyzer) .The corrosion of reinforcement in concrete is an electrochemical process. It generates electricity to cause metal dissociated.If the resistance rate is lower, the corrosion current through the concrete will be easier, the corrosion possibility will be greater. So, to test the resistivity of the concrete can effectively evaluate its corrosion resistance and evaluate the existing corrosion degree.
