WTS - Model WERT-60/120/4B -2D Resitivity Imaging System
WGMD-4 is a new state-of-art ‘Multi-Electrode Resistivity Imaging System.’ It has multiple functions such as high accuracy, quick operation, high reliability, and excellent expandability. It makes field surveys more economical and comfortable. It has the coupling unit of Mainframe (WDJD-4) and Multiplex Switcher (WDZJ-4 or WERT System) designed explicitly for resistivity imaging survey. Multi-Electrode Switcher is available in two configurations, namely WERT-60 (Supports up to 60 electrodes) and WERT-120 (Supports up to 120 electrodes), respectively. WERT -60/120 arrangements are compatible to work with the Centralized Cable System (30 take-out Resistivity Imaging cable is available at 2m, 5m, 10m, and 20m standard spacing).
Moreover, the WDJD-4 mainframe has an add-on provision to advance and use with Distributed Cable configuration ( 10 take out Resistivity & IP Imaging Cable at 2m, 5m, and 10m standard spacing), which makes sure to develop a lengthy profile for more profound mapping of earth resources, without limitation of electrodes.

- 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 6600w (1100v×6A) power, 48Vp-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 ±10V.
- 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 inputted or called. Geometric factor K can also be generated automatically or calculated manually.For multi-electrode 2D resistivity imaging, up to 18 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 100 groups of electrode distances, avoiding repetitive input. Or you just input 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 5,000,000 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.
