Resistance probe measurement can track the corrosion behavior of metal surface in real environment. It can also master the corrosion rate and corrosion condition. Therefore, we can take corresponding anti-corrosion measures in time. Or take timely measures to control the corrosion rate within the required range. The establishment of resistance probe measurement method can timely display the corrosion of equipment and pipelines, quickly find abnormal corrosion conditions, and avoid safety production caused by equipment corrosion. It is an effective corrosion detection method.
