Dzq Series Seismic Survey By Refraction Method - China

Specifications

It’ also used as a data acquisition system for multi-

channel surface wave analysis.

Application:

DZQ Series Seismic Survey is a portable and cost effective

6- 48 channel seismograph for refraction exploration,

downhole PS logging and crosshole seismic for engineering

and construction.

This is also used as a data acquisition system for multi-

channel surface wave analysis.

The system is compact, light in weight to transport and do

the job with a smaller 12VDC battery anywhere.

It’s based on the Windows XP SP2 professional with XGA/ TFT

color display, Hard disk drive, USB2.0 ports with higher

quality and reliable field performance.
