Product Overview

Functions

Customized for the specific needs of research and teaching projects.

Measurement Parameters

The GD research-grade electrical workbench is the single-channel model of the GD series (upgradable to multi-channel) — a portable high-density resistivity instrument integrating a transmitter unit, a receiver unit and a built-in boost module. The system consists of the main unit, the built-in boost module, high-density cables with switching units, stainless-steel electrodes, an acquisition terminal and a DIGspace platform account (Basic). It supports more than 1000 electrode takeouts. Featuring square-wave transmission and 24-bit A/D acquisition, with GPS + BeiDou dual-mode timing synchronization (30 ns timing accuracy), it serves ground high-density resistivity imaging, IP sounding and long-period time-lapse monitoring.

In-depth Look

Sensitivity starting at 2 nV

24-bit A/D with 1/8~128 gain and ±10 V SP compensation keeps weak polarization signals from being swallowed by noise and self-potential.

Push power-line noise into the floor

Software-selectable 50/60 Hz rejection ≥120 dB; only -0.6 dB attenuation at 10 Hz and -160 dB at 512 Hz, so the useful band is almost distortion-free.

20 time windows filled in one acquisition

The decay curve captures up to 20 time windows with 1~255 stacked iterations, giving the full decay shape rather than a few isolated points.

Excellent Signal Processing

Equipped with ±10V hardware SP compensation to effectively avoid spontaneous-potential interference and keep weak valid signals from being masked; hardware auto-gain over a 1/8~128 range adapts to input signals of different strengths.

Background Noise Made Visible

Measurement also records the full 100 Hz waveform of the background voltage time series, so afterwards you can go back and ask: is this anomaly geology, or interference?

Overall Feature Advantages

Supports real-time monitoring of time-lapse acquisition and online inversion with automatic mapping. The unit reaches IP66 protection, with over-current, over-voltage, short-circuit, high-temperature and lightning protection for harsh field environments; supports WiFi and Ethernet dual-mode data transfer with a mobile APP for easy operation.

High-density cables are core accessories for high-density electrical surveys. Multiple taps connect to electrodes and transmit subsurface electric-field signals to the cable head for acquisition and switching. Copper-core + TPU jacket is flexible and tensile-resistant, suited to complex field deployment; max transmit voltage 800V, max transmit current 2A, compatible with the entire 1st-to-3rd-generation resistivity product line. The cable family is divided into centralized and distributed by structure; centralized is further split by scenario into land, water-surface and underwater/borehole; each sub-class is split into single-tap and dual-tap by tap type.

The land high-density cable is the standard signal cable for land electrical surveys. It connects to electrodes through taps, and all tap signals are carried along a single cable to the main unit. Copper core + TPU jacket, flexible and tensile-resistant, max transmit voltage 800V, max transmit current 2.5A; tap spacing from 0.5m to 20m and 5/10/15/30/60-tap versions, split into single-tap and dual-tap types, suited to land electrical profiling and areal measurement. Single-tap cables use one tap per position, each connected to an electrode through an independent channel — simple in structure, easy to maintain, and the mainstream configuration for high-density surveys.
