Proceq Profometer-Corrosion Analysis Instrument
The half-cell method is used to identify active corrosion of rebars based on the electro chemical properties of reinforced concrete.
All the Proceq electrodes (rod or wheel) are based on a Copper / Copper Sulphate (Cu/CuSO4) half-cell.
However specific applications or customer preferences sometimes require different reference electrodes. This is why the Profometer Corrosion voltage input range allows also the connection of Silver / Silver Chloride (Ag/AgCl) electrodes or Saturated Calomel (Hg/Hg2Cl2) reference electrode.
Standard cable supplied with the Proceq rod electrode can be easily connected to most third party rod electrodes allowing the full compatibility of the system.
The detection of the hot spots where active corrosion begins involves the measuring of the localized negative values of the halfcell potential (i.e. corrosion potential). When using a rod electrode the user has to define a grid fine enough not to miss any local negative peak, while the use of a wheel electrode on the new Profometer Profometer Corrosion ensures a new level of accuracy.
The wheel system is fast enough to measure the electrical potential continuously along its linear paths, ensuring the most negative measured value will always be recognized and stored with its associated location.
