SST acoustic logging tool (compatible with 521 and other domestic CNC systerms)
It is a instrument of the small domestic CNC system for combination logging .
It could be used directly in 3700 systems ,521 systems , domestic system such as xinxiang 3000 system .
The waveform is stability when logging , interference is small ,logging-curve expectation is high.
