| Multi-technique Approach: Each
individual corrosion monitoring technique invariably has some limitations. It is therefore
often advantageous to monitor industrial corrosion processes with a multi-technique
approach. These corrosion problems are typically complex phenomena, affected by many
variables and not necessarily restricted to one form of corrosion.
The "cost" of adding techniques to an industrial monitoring program may
actually be insignificant when the overall cost of in-house expertise, external
consultants, project management, corrosion sensors, sensors for process variables,
cabling, instrumentation enclosures and intrinsic safety measures, computing and
communication systems, data analysis and reporting is considered.
Possible benefits of multi-technique
monitoring include:
Ability to monitor different forms of corrosion.
Greater confidence in data.
More data and data correlation to provide "complete picture"
of corroding system.
"Early warning" from highly sensitive techniques.
Improved overall accuracy and control.

By simply providing additional sensor elements in an electrochemical corrosion probe,
multiple electrochemical techniques can be applied simultaneously at a probe location.
