Hammer Test Silver Schmidt
Concrete Test Hammer - SilverSchmidt
The SilverSchmidt ST/PC is the first integrated concrete test hammer featuring true rebound value and unmatched repeatability.
Two factors contribute to the improved performance of this concrete test hammer over its predecessors:
Velocity based detection of the rebound quotient
The lightweight hybrid design of the impact plunger is made from aerospace alloy, matched to the elastic properties of the concrete and equipped with a hardness steel cap
Independent validation testing by BAM (Federal Institute for Materials Research and Testing, Germany) has shown the SilverSchmidt ST/PC to have less dispersion than the classical concrete test hammer over the entire range.
The unique design and high quality construction of the concrete test hammer SilverSchmidt ST/PC makes rebound hammer testing quicker and more accurate than ever before.
Features
The SilverSchmidt ST/PC concrete test hammer combines a high measurement accuracy with an unmatched repeatability.
The rebound value requires no angular correction
The concrete test hammer offers customer 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 100 N/mm2, 14’500 psi)
A large number of measurement points can be easily collected by the concrete test hammer and automatically evaluated according to statistical data
The concrete test hammer offers automatic conversion to the required measurement unit (MPa, N/mm2, kg/cm2, psi)
Ideally suited for on-site tests of concrete
The concrete test hammer is suitable for testing a wide variety of concrete, mortar and rock, but also for testing metal castings
Handy for difficult to access or confined test areas (i.e. working overhead)
Assessment on young, soft concrete with mushroom plunger of the concrete test hammer, eg. asphalt strength testing
