Rock testing

Proceq instruments are widely used  in applications for non-destructive testing of rock properties. For example: On site assessment of rock strength for drilling productivity assessment with a SilverSchmidt or Original Schmidt rebound hammer. Characterization of surface hardness for weathering studies using either a SilverSchmidt or  Equotip device. Characterization of rocks  and determination of elastic modulus with the Pundit Lab ultrasonic pulse velocity instrument. Correlation of rock hardness measurements with other parameters for core analysis using the Equotip instrument.

Equotip3

SilverSchmidt

The Equotip 3 provides a lower impact energy than the rebound hammer for  fragile test subjects or brittle samples such as the sandstone surface seen here.
 

The SilverSchmidt L rebound hammer combines unmatched accuracy in determination of surface hardness, with the possibility to implement user defined correlations to compressive strength.
 

Pundit Lab Plus

The Pundit Lab ultrasonic test instrument may be used for characterisation of rocks. When using both P&S wave transducers, it may be used to determine the elastic modulus of rock samples.
