Technical topics: Electrochemical measurements - Are they any use?

Electrochemical measurements on corrosion give a numerical indication of the rate of corrosion activity. However, the use of this technique in the industry is not common because of the uncertainty surrounding the quantity that needs measurement, the system to be measured needs to be well characterized and the chemistry should be known, the equipment should be calibrated and the technique is also perceived to be complexity. Nevertheless, progress is being made to popularize the use of the method.
