Sonic Viewer SX

The Sonic Viewer-SX is an instrument to figure out P-wave and S-wave velocities by measuring the travel time of ultrasonic wave through a boring core or a rock specimen with high accuracy, and further is capable of calculating such factors as dynamic Poisson’s ratio and dynamic elastic coefficient.

For measurements, a specimen is sandwiched between two transducers, high voltage pulse is applied to one transducer for the generation of ultrasonic wave and, then, another transducer receives the wave propagating through the specimen. Waveform data is displayed on its color LCD, and propagation time can be read out from the waveform with a high degree of accuracy.


■ P-wave and S-wave travel time can be read out accurately from waveform data

■ Signal to Noise ratio can be improved by its digital stacking function

■ Data can be copied into a USB memory stick easily from its internal hard disk

■ It has functions to figure out dynamic poisson's ratio, dynamic shear elastic modulus and dynamic elastic modulus
