Geophysical Instrument for SP Method and Geophysical Resistivity Meter

Geophysical Resistivity Meter for Water Resource Detection 0-500M Digital DC resistivity instrument It is a new generation intelligence multi-electrode resistivity instrument. It can automatically measure and memorize voltage, current, apparent resistivity, and SP parameter. 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. It also can be applied in engineering
