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, 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
 
- It can be even used for underwater applications
 
- Combining Methods to Evaluate Concrete Strength
 
- Concrete test hammer SilverSchmidt Type ST N - Standard impact energy (2.207 Nm)
 
- Concrete test hammer SilverSchmidt Type ST L - Reduced impact energy (0.735 Nm)
 
- Concrete
 test hammer SilverSchmidt Type PC N - Standard impact energy (2.207 Nm)
 with PC communication, increased memory capacity and Hammerlink 
software
 
- Concrete test hammer SilverSchmidt Type PC L- Reduced 
impact energy (0.735 Nm) with PC communication, increased memory 
capacity and Hammerlink software
 
The following standards can be applied to the concrete test hammer:
- EN12504-2 (European Standard)
 
- ASTM C 805 (North American Standard)
 
- JGJ/T 23-2001 (Chinese Standard)
