Cor Map-half cell method

Problems related to the durability of concrete are considered increasingly important as they are closely related to the quality of the structure as a whole.

Corrosion is an electrochemical process, which takes place in concrete in the presence of oxygen.

The measurements made by the Cor Map device allow the mapping of equipotential contour lines on a grid and the drawing of lines, highlighting areas of possible corrosive activity.

The Cor Map apparatus is a simple and inexpensive method of identifying areas of probable corrosion in reinforcing bars such as bridge decks, covered establishments, concrete piers and decks, substructure, tunnel lining and foundations.

The equipment consists of the following elements:

-High impedance voltmeter
-Electrode extension
-Reference electrode with copper sulfate deposit
-Copper sulfate container (250 ml capacity)
-Wetting agent reservoir (125 ml capacity)
-Dispensing sponge
-Reel with 80 m of cable
-Carrying case

Case dimensions: 50x420x190 mm
