SCPC: Determination of the Cathodic Protection

SCPC: Determination of the Cathodic Protection

Description - The SCPC logger provides in situ the value of current density necessary to protect an immerged metallic structure. It allows to determine the characteristics of the cathodic protection needed such as size, number of sacrificial anodes or power supply.

AirCorr: Corrosion

AirCorr: Corrosion

Description - AirCorr measures and registers the change over time in the electrical resistance (ER) of a thin metal track applied on an insulating substrate. If the metal corrodes, the cross-selectional area of the track decreases and the ER increases. The changes in ER can be directly translated into corrosion depth and corrosion rate.
