pic-top-1

 The PIK-UZ facility is a benchtop device performing the measurement of longitudinal and transverse acoustic waves velocity in rock samples in atmospheric conditions. The complex makes it possible to determine the velocity of P- and S- acoustic waves through a saturated rock sample and draw an inference as to mechanical properties of the sample, such as Young's modulus and Poisson's ratio.

 

 

Key features of the system:
  • Rapid sample displacement
  • Index timing of the initial wave onset
