Surface Electrical Resistivity Meter

Surface Electrical Resistivity Meter

Surface Resistivity is a laboratory non-destructive test device for rapid, easy and accurate measurement of the surface electrical resistivity of concrete based on the four-probe technique according to AASHTO TP 95-11, and pending ASTM specifications. Surface Resistivity has a unique and customized setup, which enables the measurement of electrical resistivity with high accuracy by reducing the duration of the test and minimizing ambient effects.

The Surface Resistivity provides a test cradle for 4"x 8" and 6" x 12" cylinders, which provides four (4) 4-sensor arrays positioned at 90° intervals around the cradle.
