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

Wireless concrete temperature sensor

Real-time temperature and maturity monitoring of concrete

SmartRock2™ is a rugged waterproof wireless sensor that allows real-time temperature and maturity monitoring of concrete. The sensor is placed in the concrete formwork (installed on the rebar) before pouring. Using the SmartRock2™ app you can view the temperature and resulting concrete strength in real-time.


Wireless Bluetooth Technology

Easily monitor sensor data wirelessly using the SmartRock app on a smartphone or tablet..

ASTM Strength Estimation

Using the ASTM C1074 standard for maturity-based strength, SmartRock2™ can accurately estimate the strength of concrete over time.

Optimize Break Tests

Concrete cylinder break tests can be minimized or eliminated using the maturity function of the SmartRock2™

Team Data Sharing

Sensor data is automatically shared and updated across your teams devices, ensuring everyone has the most updated results.

Real-time data made easy
Tag sensor
Label the sensor with the tag indicating its location both on the sensor and in the mobile app.
Install sensor
Once onsite, attach the SmartRock2 sensor to the rebar by twisting the metal wires together. This will activate the sensor, measuring concrete temperature and strength
Pour concrete
After installing the sensor in the formwork, pour concrete as usual.
Obtain results
At any time, wirelessly connect to the SmartRock2 sensor, and view the temperature and strength.
Reduce labour costs
The hassle of connecting to wired data loggers are a thing of the past. With the wireless abilities of the SmartRock2 sensor, any colleague with a smartphone can visit site and instantly share concrete sensor data with the team.
Full PDF reports generated in the app save significant time in the post-processing of data.

Optimize formwork removal
With the continous concrete temperature monitoring of the SmartRock2 sensor, concrete strength and maturity is automatically calculated. This allows you to more efficiently schedule construction operations such as formwork removal, saving you time and money.
