The Galvanostatic Pulse Measurements technique (GPM) was first used in the field in 1988. It provides a solution to interpretation problems found when the half-cell potential methods is used in some environments, e.g. in wet concrete.
Since the introduction development work has been conducted in order to use the technique to estimation of corrosion rate as well, which means how much reinforcement steel is being dissolved per year. Today, the GalvaPulse™ is a rapid, non-destructive polarization technique for the evaluation of reinforcement corrosion rate as well as half-cell potentials.
The GalvaPulse™ is a lightweight system supplied with batteries for optimum portability and is designed to be operated by one man.
