Giatec Surf Concrete Durface Resistivity

Model:Giatec Surf Concrete Durface Resistivity
Country of Origin:Canada
Use: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.

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 Surf™ 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 TP95 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.

The electrical resistivity of concrete is correlated well with important durability parameters such as permeability, diffusivity and in general the micro-structure characteristics of concrete. It is a fast and easy method of quality control during new construction.

Surf™ is a unique device for automatic 4-channel resistivity measurement suitable for investigating the micro-structural properties of concrete including:

  • Durability-based quality control of concrete
  • Diffusion of chloride in concrete
  • Setting time of fresh concrete
  • Crack detection in concrete
  • Water content in fresh concrete
