Corrosion monitoring can be conducted either periodically or continuously, with the monitoring frequency being influenced by the chosen monitoring technique, the extent of corrosion on the target component, and the associated monitoring expenses. The corrosion monitoring approach dictates the speed at which corrosion rates can be assessed. For instance, while corrosion coupons typically necessitate monitoring intervals exceeding a month, resistance probes can offer more frequent readings, ranging from hours to days.

​Over the years, the technology behind electrical resistance probes has undergone significant advancements, transforming it from its early manual and portable form to an advanced automatic recording system capable of online monitoring. This evolution has made resistance probe monitoring a standard practice in China's refining sector post-2000. The technology is highly regarded for its exceptional sensitivity, rapid response, robust anti-interference capabilities, and broad applicability.

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.
