R = 10 MΩ) to the steel reinforcement and is moved in a grid over the concrete surface. The reference electrode of the Canin system is a Cu/CuSO half-cell. It consists of a copper rod immersed in a saturated copper sulphate solution, which maintains a constant, known potential. © 2012 by Proceq SA... -
Page 6: Factors Affecting The Potential Measurement
Without checking the actual corrosion state this may lead to misinterpretation of the potential data. The air permeability of the concrete may be tested with Proceq’s Torrent instrument. Application Limits of the Potential Measurement Technique The potential field measurement even with a coarse grid delivers good results for chloride induced corrosion. -

In this case the measuring grid must be made finer, in order to be able to locate an anode with a very steep gradient. However, the more potentials may be misinterpreted as passive areas when only considering the absolute value of the potential. © 2012 by Proceq SA... -

Getting Started Note: First time user: Complete the tutorial OR see a demo by a qualified Proceq representative. Prepare the electrode(s) Rod Electrode - Before filling, remove the cap with the wooden plug and soak it in water for about an hour to allow the wood to saturate and swell. -

In the case of the wheel electrode with its continual automatic measurement, it is not possible to monitor whether or not the measured value is stable. Therefore it is recommended to pre-moisten the surface section wise and to measure in intervals of a few minutes. © 2012 by Proceq SA... -

Once these cursor lines have been set, the surfaces in this potential range will be automatically displayed in the corresponding colour in the CANIN ProVista “Chipping Plot”. In the example the red cursor line marks this threshold. A typical “Chipping Plot” taken from a practi- cal example is shown below. © 2012 by Proceq SA... -

Prior to making the opening it is recommended to locate the exact posi- tion of the reinforcement bars by means of a rebar locator (e.g. Proceq’s Profometer, Profoscope). Moreover a fine measurement with the Rod Electrode using a small grid is recommended to deter- mine the actual “Hotspot”... - Page 18 Fig 5.1 Menu Overview for Potential Measuring © 2012 by Proceq SA...
