There is often some confusion between the words “monitoring” and “inspection” when used in reference to measuring metal loss and calculating corrosion ratesin industrial applicationssuch as oil and gas, water treatment, chemical plants etc.

The two words are often interchanged however there is a distinct difference between the two. Inspection implies less frequent check points to assess for changes or deviations to the anticipated or required results. Monitoring is defined as checking continuously for the purpose of control in order to react quickly to change.
