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 high measurement accuracy with 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)

Applications

• Ideally suited for on-site tests of concrete
• The concrete test hammer is suitable for testing a wide variety of concrete, mortar and rock
• Handy for confined test areas or for areas that are difficult to access (i.e. working overhead)
• Assessment on young, soft concrete with mushroom plunger of the concrete test hammer
