Corrosion losses are measured for a variety of research, safety and economic reasons. The Techniques employed may be classified in many ways although the most basic distinction is between physical measurements of material present and the monitoring of reaction dates. The former is typified by ultrasonic of radio-graphic techniques or possibly direct measurements of weight loss or pit depth. Less direct methods may utilise change in vibration frequency of a corroding reed, count rate variation of a corroding layer, change in resistance of a corroding wire, strip or tube, measurement of evolved gas or even concentration of corrosion produced ions.

This paper considers various corrosion measuring techniques and the reasons for choosing one or more techniques in any particular situation.
