Concrete Testing Equipment

DZL-4000 Concrete Resistivity Tester

The concrete resistivity meter, also known as a potential‑measuring instrument (corrosion analyzer), is used to assess the corrosion of reinforcing steel in concrete. Corrosion is an electrochemical process that generates current, leading to metal dissolution. The lower the concrete’s resistivity, the easier it is for corrosion currents to pass through, and the greater the likelihood of corrosion. Therefore, measuring concrete resistivity provides an effective means of evaluating its corrosion‑resistance performance and assessing the extent of existing reinforcement corrosion.
