The Silver Schmidt 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 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 Silver Schmidt 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 Silver Schmidt ST/PC makes rebound hammer testing quicker and more accurate than ever before.
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).
The Silver Schmidt ST/PC concrete test hammer combines a high measurement accuracy with an unmatched repeatability.
Complies to EN 12504-2 (BS 1881-202), ASTM C805/C805M.
