Wireless Concrete Resistivity

Giatec SmartBox™ is a compact wireless device for the measurement and monitoring of electrical resistance and temperature in fresh concrete. The continuous measurements are recorded on SmartBox™ and can be downloaded using the mobile application on Android smartphone/tablet.

The electrical resistivity of fresh concrete has been shown to provide a good indication on the water content as well as setting and hardening of concrete. SmartBox™ provides an efficient tool for various research studies in these areas.


The SmartBox™ concrete testing equipment can be used to monitor the electrical resistivity and temperature of fresh concrete. This can provide information on:

  • Water content in fresh concrete
  • Prediction of setting
  • Setting time measurement
  • Crack detection in concrete


  • Wireless technology
  • Compact design
  • Simultaneous measurement of electrical resistance and temperature
  • Optimized frequency for fresh concrete
  • Long battery life on a single charge(about 3 months*)
  • Mobile application for Android smartphone and tablet
  • Easy data sharing
  • Patent pending


This method of resistivity measurement is not standardized and is suitable for various research applications. However, AASHTO TP 95-11 provides the test standard for surface electrical resistivity measurement. An ASTM standard is also under development for this test.
