The PRD pressure-dilatometer was developed entirely by Igeotest R&D. The device allows management and automation of testing and calibration, as well as the storage in electronic format and transmission via e-mail of the data obtained.

Applications

  • Determination of shear modulus, G

  • Determination of flow pressure
