Resistivity (ABEM)

ABEM Terrameter LS

A completely new concept of geo-electrical equipment.  The instrument lets you check your data on site in the field thanks to a large, 213 mm. (8.4 inch), colour screen that is extremely visible in daylight.  You can plot your pseudo-sections as you go.  Further to that, the instrument handles up to 12 input channels for highest possible flexibility and productivity for both 2, 3 and 4 D measurements.  Terrameter LS has two more channels dedicated to QC of the instrument performance.  Full waveform records are stored to allow for an unmatched potential of post-processing possibilities.

Automatic System for Resistivity and IP Imaging

• ABEM Terrameter LUND Imaging System – designed for optimum versatility in infrastructure projects and environmental studies.
• Built-in quality control and feedback to operator.
• Supports arbitrary cable arrangements and electrode arrays (including Wenner, Schlumberger, gradient, dipole-dipole, pole-dipole, pole-pole, square array, borehole, etc.) via user defined cable description and protocol files.
• Automated roll-along capability for 2D and 3D surveys.
• High productivity rate thanks to speed-optimised software (particularly in 4 channel version).
• Software includes data transfer from instrument to PC, protocol generation software, file conversion software and pseudo section plotting.

Terrameter SAS 1000 and 4000

Resistivity, IP and SP at highest possible productivity using the SAS 1000 for single channel acquisition and SAS 4000 for 4 channel acquisition.

• User friendly
• Utility software for Windows
• Large internal memory capacity
• Ruggedized and weather proofed
• Automatic smart-node system
• True roll-along imaging
• Output upto 1000 mA
• Can be used with the SAS LOG for borehole logging

SAS LOG

The SAS LOG accessory connects to Terrameter SAS 1000 or 4000 and converts it to a logging system for resistivity and IP in a water filled borehole.  In addition to that, it also measures the temperature and SP as well as gives an indication of when the water level is reached. 

The log cable has fixed electrodes and at the bottom end a sonde with the sensors for the other parameters.  The cable is marked in one metre increments, is lowered manually into the hole step by step.  Readings are taken at each step by activating the measure knob of the Terrameter.  Data is stored in the memory of the Terrameter for subsequent processing and plotting in a computer with suitable software like for example LogPlot from Rockware.
