The IoT Meter / IoT Sensor is a measuring tool for testing the strength of concrete. The IoT Meter / IoT Sensor measures strength according to the Schmidt principle. According to this measurement method, the quality of concrete can be measured with the IoT Meter / IoT Sensor. Thus, the IoT Meter / IoT Sensor finds its essential application in construction and in the construction sector. The IoT Meter / IoT Sensor is also suitable for measuring the hardness of rolled paper. The built-in mechanism on the IoT Meter / IoT Sensor always ensures the same impact energy of 2.207 Nm.
The hardness tester displays measurements Rebound Value and can display force in PSI, MPa, kgF/cm², or N/mm². The IoT Meter / IoT Sensor can be set up to measure at test angles of downward(-90°), downward(-45°), horizontal (0°), upward(45°), or upward(90°).
