The engineers at HGCR have been hard at work improving the sensor range, battery life, and speed.  With VAKKA 2.0, we have increased the speed 5 times.  Now you can spend less time waiting and make decisions faster.  With all VAKKA sensors, accuracy matters.   

VAKKA is a durable, waterproof concrete sensor that wirelessly monitors the environmental conditions within the concrete as it hardens. Install the sensor before concrete placement to record temperature and relative humidity. Our patent-pending environmental chamber is unique to the VAKKA system and allows faster and more accurate readings. In addition, it quickly equalizes the surrounding environment, recording measurements within one hour of pouring your concrete.

Our free mobile app and cloud service empower your team to make more confident decisions faster. Your data can be downloaded to the app at any time when a connected device is within the sensor's range and instantly uploaded to the cloud, where it is shared with your team. The app will automatically do the heavy lifting by calculating your calibrated compressive strength and maturity curve, allowing instant access to your temperature and relative humidity readings, plotting your data, and generating reports.
