The use of corrosion monitoring systems helps to detect early signs of corrosion before failure so that proper maintenance can be performed to prevent catastrophe. Weight-loss coupon and Electrical Resistance (ER) techniques are typically used for corrosion monitoring in oil/gas, refinery, chemical processing, etc.

The weight-Loss Coupon (WL) technique is the most accurate corrosion monitoring method among all the existing corrosion monitoring methods. However, the weight-loss coupon technique typically requires a long exposure time (at least 90 days) for the measurement. This means that continuous in-situ monitoring is not possible and the effects of corrosion dynamics cannot be isolated.

The advantages of ER technique are usable in any environment, continuous in-situ monitoring, and detectable in the change of corrosion rate. However, the ER technique cannot detect a localized corrosion. The ER technique can show us only uniform corrosion.

NexCorr successfully developed and tested innovative corrosion monitoring system to detect real-time pitting corrosion (Patented Technology).

NexCorr provides three corrosion monitoring systems as follows:

1. PDS (Pit Detection Corrosion Monitoring System)
2. MFS (Multi-functional Corrosion Monitoring System, PDS + AI ER (i-ER))
3. AI ER (i-ER) (Electrical Resistance Monitoring System based on Artificial Intelligence)

All corrosion monitoring systems consist of a probe, an adapter, a transmitter, and software.
