WZG-24/48C geophysical survey equipment for sale Refraction Seismograph
Seismic waves are generated using methods like hammer strikes, electric sparks, or controlled explosions, allowing exploration depths ranging from a few meters to hundreds of meters. With a delay feature for deeper subsurface investigations, this tool is ideal for a variety of seismic tasks such as reflection and refraction studies, surface wave analysis, foundation testing, ground motion assessments, seismic imaging, vibration monitoring, and shear wave velocity measurements.
Its broad applicability spans numerous industries, including water conservancy, power generation, railway and bridge construction, urban development, transportation, and engineering geophysics. Moreover, it plays a crucial role in resource exploration for sectors like petroleum, coalfields, uranium mining, and groundwater resources.
