price: contact company for price

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.
