The roll hardness tester is an analog measuring device to determine concrete strength. The measuring method of the roll hardness tester is based on the Schmidt principle. With this measuring method, a kinetic impact energy hits the concrete from the roll hardness tester. The resulting rebound enables the roll hardness tester to determine the strength of the concrete.

- Nominal kinetic energy: 4.5 J
- For high-strength concrete
- Simple and quick operation
- For determining concrete hardness
- Schmidt principle
