Silver Schmidt Test Hammer (Proceq)

Silver Schmidt Test Hammer (Proceq) is the world’s most advanced rebound hammer fully adapted specifically to the extremely varied concrete testing applications (Testing on cores and blocks). The Silver Schmidt incorporates statistical methods based on ASTM and ISRM recommendations and provides the user with the freedom to define his own statistical process for determining a rebound number.

The Silver Schmidt Concrete Test Hammer is supplied complete with:

  • Battery Charger with USB Cable
  • Carrying Strap
  • DVD with PC software
  • Grinding Stone
  • Documentation
  • Carrying Bag
  • Standards

  • EN 12504-2
  • EN 13791
  • ASTM C805
  • JGJ/T 23-2001
  • Key Features

  • Impact Angle Independence: The rebound value is independent of the impact direction
  • Optimised for Field Work: Tighter sealing against dirt and dust intrusion for longer life. Significantly lighter and more ergonomic than the classic Schmidt hammer. A large number of readings can be saved and downloaded later to a PC
  • Preset Statistics: Statistics methods recommended by ISRM and ASTM are implemented into the hammer for automatic calculation of the rebound number. The option is also there to define a user specific statistics method
  • Unconfined Compressive Strength: ISRM recommends a correlation between UCS and the rebound value based on the formula UCS = aebR (where R is the rebound value). A correlation in this format may be defined in the PC software and downloaded onto the RockSchmidt
  • E-Modulus: ISRM recommends a correlation between elastic modulus and the rebound value based on the formula Et = cedR (where R is the rebound value). A correlation in this format may be defined in the PC software and downloaded onto the RockSchmidt
  • Weathering Grade: Impacting on the same location twice can be used to correlate to weathering grade. The ISRM recommended method has been included in the device
