Giatec Surf™ Surface Resistivity

Supports the following standards: ASHTO TP-95

Surf™ 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 (Wenner-Array) technique according to AASHTO TP 95-11, and pending ASTM specifications. Surf™ 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 Surf™ 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. Surf™'s patented technology automatically takes measurements at each of the sensor points around the cylinder and then repeats the process for all 8 measurements in less than 15 seconds. The included PC software takes this information and generates the reports required by the standards.

Applications:

  • Performance-based, quality control testing
  • Estimation of chloride diffusion coefficient
  • Service-life design of concrete structures
  • Remaining life estimation of structures
  • Crack detection in under load concrete
  • Monitoring the setting time of fresh concrete

Features:

  • Patented technology
  • Fully compliant with both AASHTO TP95 and the upcoming ASTM standard
  • Fast measurement (8 measurements < 15s)
  • Four-channel surface resistivity meter
  • Variable frequency (13 - 100 Hz)
  • Limits moisture loss
  • Automatic report generation with PC software
