Geophysical Resistivity Imaging, vertical electrical sounding and water finder

Application:

 1. Geophysical Resistivity Imaging, vertical electrical sounding and water finder is a new generation intelligence multi-electrode resistivity instrument.

2. It can automatically measure and memorize voltage, current, apparent resistivity, and SP parameter.

3.It is widely used in the hydrological and engineering survey, such as ground water seeking; dam base evaluation and flood control dam incipient fault and so on.

4. It also can be applied in engineering geological prospecting, such as metal-nonmetal mineral resources exploration, urban exploration, railway and bridge, even in the geothermal exploration.
