Proceq Profometer-Corrosion Analysis Instrument
As the direct successor to the Canin, the Proceq Profometer Corrosion represents the most advanced corrosion instrument in the market based on the half-cell method.
In addition to the basic rod electrode, the use of Proceq’ s unique one and four wheel electrodes enables the highest on site productivity on large areas.
- Intuitive user friendly interface for data acquisition
- Buttons indicate measuring path direction
- Optimized workflow for rod and wheel measurements
- Customizable text can be entered for the specific locations
- Flexible features enable the mapping of any irregular geometry
- Improved digital filtering to remove the effect of external noise (civil and industrial power sources)
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.
The 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.
