WGMD-4 ERI System

Product Description

Application:
• Metal and nonmetal mineral resources detection
• City geophysical exploration, railway and bridge inspection
• Hydrology and engineering geology as seeking for ground water, inspecting dam base and flood protection levee for incipient faults
• Geothermal prospecting

Function:
• 1D resistivity sounding
• 1D induced polarization sounding
• 2D Resistivity imaging

Main Features:
• Transmitting unit and receiving unit are of all-in-one design, portable and lightweight.
• Super high-power, high anti-interference performance and precision: up to ***0w (***0v×6A) power, *8Vp-p voltage range ensures to get a good result in a area with high resistance.
• Automatically achieving compensation of self-potential, drift and electrode polarization, up to ±*0V.
• Receiving unit support transient over-voltage protection, transmitting unit supports over-voltage protection, over-current protection and AB open-circuit protection.
• For general resistivity and IP survey function, 9 types of electrode arrays are available. Electrode distance (namely “Program”) can be ted or called. Geometric factor K can also be generated automatically or calculated manually.
For multi-electrode 2D resistivity imaging, up to *8 electrode arrays are available. It could scanning measure according to fixed section (including AMNB, ABMN, AMBN, AMN, MNB, A-MN-B, Sp M, Sp MN, charge M, charge MN) or continuous rolling scanning measure according to variable section (including A-M, A-MN, AB-M, AB-MN, MN-B, A-MN rectangle).
• Program: the program can memorize **0 groups of electrode distances, avoiding repetitive . Or you just a program Id and step to call the corresponding electrode distances.
• Earth resistance inspection: ground condition can be inspected at any time.
• Mass data storage: Up to 1GB capacity (extended) enable store 5,**0,**0 groups measuring data (including current, voltage, SP, Ro, Ms, metal factor, TH, R, J).
• All parameter and data are under power-failure protection; and thus data will not be lost even thought the system shuts down accidentally.
• USB port enables it to transfer data to computer.
