ERTLab™ is the 3D resistivity and chargeability inversion software that has radically changed the approach to electrical resistivity tomography (ERT) surveys, allowing full flexibility in the three-dimensional arrangement of the electrodes and creating the market of resistivity surveys around buildings. Available for both 32 and 64 bits platforms (with multi-threading capabilities), ERTLab™ is able to invert ERT measurements for any array geometry - surface, cross-hole or surface-to-hole. ERTLab™ makes use of Finite Elements algorithm for the accurate modeling of the terrain topography. Improve the way you perform resistivity and broaden the application of ERT surveys to new markets. Invert faster and manage huge sets of electrodes and measurements. Request a DEMO version. For the American market please refer to our partner and co-developer.

ARES II - ARES II represents a well equipped resistivity and IP imaging system. Its advantages can be applied especially for large 2D and 3D surveys (operating up to 65,000 electrodes), for continuous survey from water level and for programable monitoring of structures. Groundwater exploration, geotechnical investigation, monitoring of dams and dikes, environmental studies, geological survey, mineral prospecting, archaeology, detecting of cavities and buried objects, underwater, marine, borehole and cross-hole measurements. JS-6A - Transmitter² oneboard computer control; accurate timing,high reliability² Large LCD, English menu, digital display ofoutput voltage, current, power supply resistance,power supply time, power supply period, thebattery voltage.² Big power supply current，overload protection² Big output voltage(1000V)MAIN SPECIFICATION:Time control Precision. EarthImager 3D - AGI is proud to introduce the new EarthImager 3D resistivity and IP inversion software.

This software inverts resistivity and IP data acquired with electrodes arranged in boreholes and/or on the surface and presents a 3D volume of inverted resistivity data with advanced volume rendering technique. The final resistivity or IP image-volume can be rotated in any orientation, zoomed in and out, and translated to anywhere inside the image window in order to see the volume of interest in detail. Colors representing areas of less interest can be made transparent so that the shape of a pollution plume, for example, can be visible.

With EarthImager, 3D resistivity inversion can be as easy as two steps: Read Data and Start Inversion with only a few mouse clicks. RES2DINV - designed to interpolate and interpret field data of electrical geophysical prospecting (2D sounding) of electrical resistivity (conductivity) and induced polarization.

The inversion of the resistivity and IP data is conducted by least-square method involving finite-element and finite-difference methods. The software can handle data from any electrode array, including Wenner (a, b, g), dipole-dipole, inline pole-dipole, pole-pole, Wenner-Schlumberger, equatorial pole-dipole and non-conventional arrays. Interpolate data from land, under water, and cross-borehole surveys.
