Standard: ASTM D6760-02
The Cross-hole Sonic Logging (CSL) method is used to perform high-resolution quality control on deep foundations.
The system uses an ultrasonic wave sent from an emitter to a receiver while both are pulled through water-filled access tubes embedded in the concrete.
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.
Easy to use: the user-friendly software makes it possible to master the instrument in less than a day.
No additional expensive training required.
Powerful tomography features are available.
