Super Geophysical Resistivity And IP Imaging System

The instrument is our newly developed product with years of research and production experience of advanced electrical tool, which includes many advanced elentronic technique such as all-chinese pocket PC, blue tooth, 24 bit A/D, and large power control. This tool has small size and light weight, and its main technique specifications and functions are more advanced than similar tools abroad and home can be applied in different complex regions. It has been applied widely in metal and non-metal mineral propecting, civil propecting, railway, bridge, etc. It can also be applied in underground water, water reservoir dam foundation, jetty hidden trouble, and geothermal exploration.
