Wireless sensor for concrete resistivity and temperature

Ref.: H0398

SmartBox™ | Wireless Concrete Resistivity

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.


SmartBox™ 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
