James Instruments, Inc. Cor-Map II
Advanced System for corrosion potential data acquisition and analysis, allowing the user to quickly identify areas of probable corrosion in the field

The fully integrated data acquisition and analysis unit has been designed for the rapid analysis of data in the field or office. As large amounts of data are normally generated, interpretation of this information can be very difficult. Employing the simple to use, menu driven CorMap™ main unit, data can not only be collected quickly and easily, but it can also be analyzed directly in the field on the graphic display. The unit produces a symbolic map of the structure, where symbols represent various half-cell potential voltage levels previously acquired. This symbolic map can then be interpreted like a contour map where areas of high potential represent areas most likely to be corroding.
Not only can this information be acquired and analyzed, but the unit will also read the general environmental parameters of temperature and relative humidity.
All this data can also be stored and uploaded to a P.C. This allows the user to include the data in subsequent reports and spreadsheets for further analysis. Each data point is also recorded with the time and date to simplify later analysis.
The Cor-Map II™ system comes complete with a rugged half-cell designed for the tough construction environment. Porous ceramic tips are used in order to provide a long life, and eliminate problems from clogs in the Cu/CuSO4 half-cell. These specially shaped tips have been designed to allow the half cell to take readings in the vertical, horizontal or inverted position.There is also a semi transparent full-view window, allowing liquid level observation without removal of the sealed ends; while still protecting the half cell from damage by sunlight.
