GS201 Distributed High Precision Land Seismograph
GS201 distributed high precision land seismograph adopt the 32-bit high precision Σ -Δ ADC，which can support 4000 channels under 1 ms sampling interval. It can be suitable for ten thousand channel 2D and 3D seismic exploration. The instruments contain industry PC, master station, cross station, acquisition station. The connection structure is very flexible and light. Exploration depth can reach from several meters to thousands of meters. And it contains is applicable to the seismic work such as reflection, refraction, surface wave exploration, pile foundation inspection, pulse, seismic imaging, vibration measurement and wave velocity (shear wave) test etc. The instrument has been widely used for different areas engineering geological exploration such as water conservancy, electricity, roads, railways, bridges, urban construction, transportation, groundwater and resources exploration such as oil, coal, coal-bed methane, shale gas, metals andnon-metallic mineral.
Through the laboratory and field-proven contrast testing, the main technical parameters have reached international advanced level, some of them are leading international.
