2D Resistivity Imaging Geophysical Exploration Instrument Portability
Intelligent 2D Geophysical Exploration Instrument for Resistivity Imaging
Main Function
WGMD-9 super digital DC resistivity/IP meter is a newly developed electrical method instrument, adopting many advanced technologies such as pocket PC, Bluetooth, 24bit A/D, and high power control. It features compact size and lightweight. Its main performance and functions are better than its similar products at home and abroad.
WDA-1/WDA-1B work with WDZj-4 or WDZJ-120 Multi Electrode Switcher can be applied in a variety of complex regions and has widely used in metal and non-metal mineral resources prospecting, city geophysical exploration, and railway and bridge inspection; in hydrology and engineering geology to inspect base of dam and flood protection levee for incipient faults. Besides, it contributes to geothermal survey.
Features
* Portability and flexibility
* Unique and open measuring process control.
* High power supply, wide current range, high accuracy
* Bluetooth technology facilitating wireless remote control
* Extendable easily
* Excellent anti-interface performance
* Pocket PC controlled and powerful function: English version pocket PC to control sampling and relevant parameters setting, data displaying and storing, graph plotting for 10 kinds of electrode array configurations (such as, 4P-VES Schlumberger, 4P-VES Wenner, Combined electric sounding, four-pole electric profiling, Combined electric profiling, Rectangle/Middle Gradient, dipole-dipole, Five-pole Longitudinal Axis Electrical Sounding, Quadratic time difference array, etc). Moreover, advance hardware enables operator to have agenda and to connect with Internet wirelessly, with software such as WORD, EXCEL, PowerPoint, Media Player and so on.
* Receiving unit supports transient over-voltage protection for input voltage; transmitting unit supports over-voltage protection, over-current protection and AB open-circuit protection as well as DC high voltage reverse connection protection.
* Earth resistance check: earth resistance of AB Current electrodes and MN Potential electrode can be inspected at any time.
