GS201 Distributed Seismograph

Product Introduction

  • The GS-201 distributed high-precision terrestrial seismometer uses a 32-bit high - precision sigma - delta ADC that supports 10,000 2D and 3D seismic surveys and supports 4000 lanes at 1 ms sampling interval . The instrument adopts the topology of industrial notebook, main control station, cross station and collection station, and is flexible and light; the exploration depth is from a few meters to several kilometers; and it is suitable for reflection, refraction, surface wave exploration, pile foundation detection, ground pulsation measurement, like, vibration measurement and velocity (shearseismic work wave) test issues; widely used in engineering geological exploration in the field of water, electricity, roads, railways, bridges, urban construction, transportation and groundwater, as well as for oil, coal, CBM, shale gas, metal and non -metallic mineral resources exploration and other fields. After laboratory and field comparative tests, the main technical indicators have reached the international advanced level, some of the indicators leading the world.
