Concrete Temperature Sensor with 3m Probe (VAKKA-T3) (40/Pk)

Introducing the revolutionary VAKKA 2.0 concrete monitoring sensor, engineered to transform how you assess and manage concrete curing. This cutting-edge sensor provides unmatched accuracy and reliability by continuously measuring relative humidity and temperature within concrete structures. Gain invaluable insights into the curing process, ensuring optimal strength development and long-term durability. Perfect for construction projects, infrastructure maintenance, and research, VAKKA 2.0 elevates concrete monitoring standards, enhancing quality control and extending the lifespan of concrete.

The engineers at HGCR have significantly improved the sensor's range, battery life, and speed. VAKKA 2.0 boasts a fivefold increase in data acquisition speed, allowing you to make critical decisions faster than ever. As with all VAKKA sensors, precision remains paramount.

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

Our free mobile app and cloud service empower your team with confident, rapid decision-making. Download data to the app when a connected device is within range, and it instantly uploads to the cloud for team sharing.
