SILVERSCHMIDT

Proceq has combined the best of Original Schmidt with the most advanced technology to create the new SilverSchmidt concrete test hammer.

The SilverSchmidt offers a virtually maintenance free, lightweight and compact construction.

This next generation tool combines an electronic display and advanced mechanics with true rebound coefficient that automatically converts to compressive strength.

Features

  • Measurement inherently independent of impact direction, meaning no directional corrections are necessary
  • High measuring accuracy due to differential optical absolute velocity encoder
  • 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 170 N/mm2, 24’650 psi)
  • Simple operation with "one-button", combined with advanced tilt and twist technology user interface
  • Language independent graphical menu with symbols 
  • Automatic conversion to the required measurement unit (N/mm2, kg/cm2, psi)

Applications

  • Suitable for testing a wide variety of concrete, mortar and rock
  • Ideally suited for on-site testing
  • Handy for difficult to access or confined test areas (i.e. working overhead)
  • Especially convenient for testing on tunnel linings as measurements are independent of impact direction
  • Assessment on young, soft concrete with mushroom plunger (to indicate when to remove forms or for formwork)

Product Variations

  • Type BN - Standard impact energy (2.207 Nm)
  • Type BL - Reduced impact energy (0.735 Nm)
  • Type UN - Standard impact energy (2.207 Nm) with PC communication and increased memory capacity
  • Type UL - Reduced impact energy (0.735 Nm) with PC communication and increased memory capacity
