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 100 N/mm², 14’500 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 (MPa, 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)
