Product Description

WDA-1 Subsurface Geophysical Resistivity Survey System
 

  WDA-1 is the most advanced resistivity meter of our company. WDA-1 works based on different materials (clay, rock, water) have distinct resistivities, to acquire apparent resistivity data from rock layers at different depths by supplying electrical current into the ground via electrodes. The WDA-1 can deliver a maximum power of 9000W (1500V × 6A) to the electrodes. When substantial currents flow through the electrodes into the ground, the WDA-1 precisely records the apparent resistivity values of different rock strata. By analyzing the variation curves of apparent resistivity, it assesses the approximate distribution of various underground rock formations. WDA-1, with its excellent resolution and low interference characteristics, enables users to create 2D/3D maps of the layered distribution of different substances underground. No matter for ground water mapping, geological surveys, bedrock profiling, geoharzard detection, dam safety and infrastructure monitoring.

Main Features

* High power output:
WDA-1 Supports high-power output up to 9000W (1500V*6A), significantly enhancing detectable depth and resolution of underground rock formations.
* Wide measurement range, high accuracy:
With an ultra-wide input voltage range of 160Vp-p and exceptional small-signal measurement accuracy (0.1mV/0.1mA @ ±1%), the instrument excels in high-resistance environments, delivering deeper and more precise measurement results.
* Advanced anti-interference technology:
Featuring multi-stage filtering and signal enhancement technology, with integrated electromagnetic interference suppression capabilities, it delivers exceptional resistance to both common-mode and differential-mode interference.
* User-friendly feature design:
Receiver overvoltage input protection, automatic natural potential, drift, and electrode polarization compensation, rapid and accurate fault diagnosis procedures, etc.
* Multifunctional:
El instrumento puede utilizarse para llevar a cabo métodos de exploración geofísica como VES, Wenner, Schumberger, tomografía de resistividad eléctrica (ERT) y polarización inducida (IP).
