CANIN+ Electrical Reinforcement Potential
/Products/Corrosion/Half-Potentials-Resistivity/Image-1.aspx) CANIN+ is for the non-destructive detection of corrosion in the reinforcement bars of concrete elements. It enables the identification of corrosion before it becomes visible and has caused damage. For the first time CANIN+ makes it possible to see a graphical plot of a large area assessment directly on the display of the measuring device. This enable the inspector to immediately mark on the concrete surface the areas of concern and to later down load the data for printing in a report. RANGE OF APPLICATIONS
The CANIN+ instrument offers a single method for investigating and assessing the corrosion of steel in concrete.
- Measurement of corrosion potential
COMPLIANCE WITH INDUSTRY STANDARDS
Data collection and processing of test results comply with major industry standards:
- ASTM C876-91
- BS 1881 Part 201
- SIA 2006, DGZfP B3
- UNI 10174
FEATURES
- Immediate presentation of test area and reading directly on the instrument display
- Optional wheel electrode for increased testing speed and productivity. Readings are collected at a predetermined spacings automatically and stored.
- Total memory for more than 200’000 readings
CORROSION POTENTIAL APPLICATION
Firstly, accurate field potential measurements aid in detecting cor¬rosion in rebars. Corrosion of steel in concrete is an electrochemical process. A potential field can be measured on the concrete surface by the use of an electrode, known as a half-cell, and a high-impedance voltmeter. The CANIN+ Corrosion Analyzing Instrument highlights cor¬rosion activity before rust becomes visible. This early detection can be a key in preventing an unanticipated structural failure.
CANIN+ is ideally suited for assessment of corrosion potentials on large areas of 8,000 m²or multiple thereof, depending on the individual selectable grid size. 235,000 values can be stored by the intelligent memory. Up to 240 measurement values are displayed at a time in easy-to read grey-scale and a menu-driven approach facilitates simple operation using just nine keys.
Interpretation of the collected readings is facilitated by the use of the CANIN ProVista software.
CANIN PROVISTA PC SOFTWARE
The Windows based software CANIN ProVista, developed by Proceq SA, makes it possible to download, present and edit data measured by the CANIN+ half-cell instrument in a fast and easy way using an IBM-compatible PC. The program generates a potential map, a relative frequency and a cumulative frequency diagram and provides a chipping graph. This statistical presentation is the basis for an efficient interpretation of the half-cell potentials by the corrosion engineer.
Single files can be opened and processed separately. By rotating or mirroring in intervals of 90° the single potential maps can be combined to form a complete graph representing the total investigated surface area.

Based on the user defined threshold potentials that represent certain conditions of the struc¬ture, up to four characteristic potential intervals can be chosen. The corresponding partial areas are marked with different colours in the presentation as a “Chipping graph“.
