Features:
- Independent of impact direction
- High measuring accuracy
- Optimum performance
Other Details:
- Measurement inherently independent of impact direction, meaning no directional corrections are necessary
- High measuring accuracy due to differential optical absolute velocity encoder
- Conversion curves for a wide range of compressive concrete strengths, including low fc (<10 N/mm2, 1’450 psi) and high strength concrete (up to 170 N/mm2, 24’650 psi)
- Simple operation with "one-button", combined with advanced tilt and twist technology user interface
- Language independent graphical menu with symbols
- Automatic conversion to the required measurement unit (N/mm2, kg/cm2, psi)
Applications:
- Suitable for testing a wide variety of concrete, mortar and rock
- Ideally suited for on-site testing
- Handy for difficult to access or confined test areas (i.e. working overhead)
- Especially convenient for testing on tunnel linings as measurements are independent of impact direction
- Assessment on young, soft concrete with mushroom plunger (to indicate when to remove forms or for formwork)
