The GD-10 series geoelectric system is a newly developed new electric system with a large breakthrough compared with similar products. It has the characteristics of large transmission power range, high signal precision, complete test function, simple and light field test wiring, and low maintenance cost for long-term use.

GD-10 is developed based on the latest digital and analog circuitry technique, making it the world leading multi-functional direct current (DC) method instrument. This equipment can be adopted in self-potential (SP), apparent resistivity and induced polarization (IP) surveys. Not only GD-10 supports regular ERT survey configurations, subsurface profiling using both 2D and 3D survey arrays are also supported. GD-10 is powerful in conventional surface ERT surveys, borehole testing, mining tunnels, marine and submarine surveys. Online monitoring mode is readily available for GD-10 to initiate remote automated survey and realize long-term unmanned field monitoring.

GD-20 is a brand new multichannel geo-electrical system, designed with 5 or 12 channels and up to maximum 10 survey points can be measured concurrently for ERT survey, highly enhancing field survey efficiency. GD-20 can be used in SP, ERT and IP surveys. Comparing to single channel instruments, GD-20 boosts ERT survey efficiency up to 2-3 times in average and lowering working duration of field survey.

Geomative electrical system offers underground ERT resistivity testing solutions, breaking through traditional 1D VES methods for well logging. The ERT well logging method simplifies the field construction and wiring, greatly improves efficiency and data comprehensiveness. It supports the acquisition of SP, resistivity, IP and other high-quality data.

Online monitoring is basically established on the basis of current measurement space (either 2D or 3D) and added the time dimension. By comparing measurement outcomes from various time slices to initial state (background values), the anomalies of the monitored target is determined from this variation over time. Derived from electrical resistivity method, Geomative Inc. developed Geomonitor Online Monitoring System.

The GS-201 distributed high-precision terrestrial seismometer uses a 32-bit high-precision Σ-Δ ADC that supports 10,000-channel 2D and 3D seismic surveys and supports 4000 channels at 1ms sampling interval. The instrument adopts the topology of industrial notebook, main control station, cross station and collection station, portable and light; the exploration depth ranges from a few meters to several kilometers.

The survey of environmental pollution sites, led by geophysical methods and regarding ERT electrical methods as the core, investigates the pollution status of typical pollution sources with the help of electromagnetic method and Ground Penetrating Radar. According to the physical and chemical differences between the pollutants and the surrounding media, the distribution of the physical sites is measured, and the distribution and migration of pollutants are deduced. The rapid, low-cost, non-destructive and systematic site survey techniques will provide a reliable basis for comprehensive site remediation and development in the future.
