Seismic Equipment DZS-1 Deep Digital Seismograph

DZS-1 Deep Digital Seismograph is a kind of 3D data acquisition device. Mainly utilizes explosion and huge seismic wave to detect the characteristics and properties of crustal deep structure; microseismic detection can also be used in the research of natural earthquakes, 3D seismic survey of oil field gas, etc, especially for long time unattended testing 

System consists of data acquisition device, zero time receiver and built-in geophone. Reflection and Refraction Exploration: Bedrock embedded depth, shape and regularities of distribution research, hydrological and engineering and environmental geological basic investigation.
