Seismograph for Wave Velocity Testing (sheared wave), Surface wave detecting, Pier foundation inspection, Ground micro-tremor survey,Seismic imaging, Shake test
Seismic source may be hammer, electric spark or explosion. It is extremely suitable for wave velocity testing (sheared wave), surface wave detecting, pier foundation inspection, ground micro-tremor survey, seismic imaging, shake measurement, and reflection and refraction survey. It is extensively applicable in hydrogeology, electric power, railway, bridge, city construction, traffic and other engineering geological field prospecting as well as in exploration of petroleum, coalfield, uranium ore, groundwater and other resources.
