Giatec Surf™ is a laboratory test device for rapid, easy and accurate measurement of the surface electrical resistivity of concrete based on the four-probe (Wenner-Array) technique. The patented technology automatically measures resistivity around the concrete specimen using four channels of 4-probe array (located at 90° from each other). The PC software generates the required reports according to the standard specifications.
Surf™ can be used to determine the chloride permeability of concrete in accordance with AASHTO TP 95 and the upcoming ASTM standard. The measurement data can be used for durability-based quality control of concrete as well as the service life design of concrete structures.
