SilverSchmidt

The new SilverSchmidt ST/PC is Proceq’s most sophisticated rebound hammer that makes concrete testing quicker and more accurate than ever before.

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.

    • 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
    • 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
