The measured arrival time and energy are directly related to concrete quality. The control unit must be connected via USB port standard to a regular notebook computer or Tablet PC (not included) on which, should be installed the software (included) for testing, analysis and real time reporting in 2 D Tomography. The Cross-hole Sonic Logging (CSL) method is used to perform high-resolution quality control on deep foundations.
