Geophysical Resistivity & IP Equipment, Geographic Surveying Instrument, Resistivity Imaging, Electrical Resistivity Tomograph for Ground Water Exploration
Application:
The Geographic Surveying 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.
Main Features:
1. Portability and flexibility: combining transmitter and receiver together, small and light.
2. Real one machine and multi-function: voltage and current range and small signal accuracy improved
greatly, it is fitted for rock sampling tester, large-power IP receiver, nomal resistivity tool, IP, water finder,
2D and 3D high-density electrical tool etc.
3. Multi-parameter measurement, wide application: voltage, current, apparent resitivity, SP, apparent
chargability, metal factor, half life, attenuation, IP ratio, departure, IP spectrum.
