Unlike current destructive methods for temperature and humidity monitoring, this sensor is non-destructive, requiring no drilling into flooring to take measurements.
BlueRock™ is a wireless sensor for monitoring the temperature and relative humidity of in-place concrete from fresh to hardened stages. Monitor variations in your concrete’s internal humidity in real-time via LTE/Wi-Fi connection using the BlueRock mobile app (available for Android/iOS devices). This data is used as a QC/QA method. By knowing the level of humidity of in-place concrete, you can optimize the timing in which floor coverings are installed, such as resilient flooring, epoxy coating, or wood.
| Temperature Reading Range | -22°F to 140°F (-30°C to 60°C) |
| Temperature Accuracy1 | ± 1.8°F (± 1°C) |
| Relative Humidity Reading Range | 0 to 100% |
| Relative Humidity Accuracy2 | 20% – 80%, ±2% <20% or >80%, ±3% Hysteresis ±1% |
| Wireless Signal Range3 | Up to 26 ft (8 m) |
| Battery Life | Up to 2 years |
1 Accuracies are tested at Outgoing Quality Control at 25°C and 3.0V. Values exclude hysteresis and long-term drift and are applicable to non-condensing environments only.
2 Normal operating range: 0-80% RH, beyond this limit sensor may read a reversible offset with slow kinetics (+3% RH after 60h at humidity >80% RH).
3 The wireless communication range is reduced as the sensor is embedded deeper in the concrete. The maximum recommended concrete depth for embedding the sensor in the field is 2 in (5 cm). At this depth, the user can communicate with the sensor within a couple of meters.
Note: Specifications are subject to change without notice.
The battery life is up to 2 years under room temperature.
No, the BlueRock is not a standardized method. If you want to learn more about the difference between the standardized method and the embedded BlueRock sensor to measure relative humidity of your concrete please contact Giatec technical support team they will gladly walk you through the difference between the two measurement methods.
The relative humidity of fresh concrete will be 100%. Only in concrete with a low water-cement ratio where self desiccation occurs (typically w/c < 0.38) will the relative humidity start dropping very quickly after the pour.
It depends on multiple factors such as the exposure conditions, the w/c ratio, the type of concrete, or the depth of the element. Typically it can range between 10 months to a year or more before the relative humidity starts dropping.
Yes, if an element is continuously exposed to the environment or a constant source of water, the relative humidity of the concrete will remain at 100%.
The BlueRock™ sensor will measure relative humidity right at the sensor location and therefore, one sensor cannot represent the condition of an entire floor. We recommend following the ASTM F2170 placement location to get the best representation of the relative humidity across a concrete element. The sensors will not be able to identify very localized spills or water infiltration unless there is a sensor at that specific location.
