The office has the following four electrical tomography systems which can perform two-dimensional and three-dimensional imaging of the subsurfaceς:

• LUND Imaging system (TERRAMETER SAS 1000 (1 channel, max output current 1A & max output power 100W) plus electrode selector ES464 (4 channel & 64 electrodes)) of the swedish company ABEM.
• LUND Imaging system (TERRAMETER SAS 4000 (4 channel, max output current 1A & max output power 100W) plus elector selector ES464 (4 channel & 64 electrodes)) of the swedish company ABEM.
• TERRAMETER LS (4 channel, 64 electrodes max output current 2.5A & max output power 250W) of the swedish company ABEM.
• MX-30 Multiplex Switch (30 channels, 30 electrodes max output current 5A & max output power 2500W), GDP-32 receiver (6 channels) και ZT 30 Transmitter (max output current 30A), of the american company ZONGE ENGINEERING.

The accessories include electrodes (sold or not) and 81 electrode electrical tomography wire, spaced 2m, 5m, 10m, 25m and 50m, which make it possible that the length of scans  be from 160m to 4000m from the beginning. At the same time, these cables allow us to apply the Roll along process, during  which a much larger number of electrodes can be used, while at the same time the profiles of the tomographies can be developed as much as necessary in order  to achieve the objectives of the geophysical research. For the interpretation and presentation of results the software used is the programs RES2DINV and RES3DINV, of GEOTOMO company.

 

The office has the base station, the Magnetometer - Gradiometer G856 and the measurement interpretation software MAGMAP and MAGPLOT, of the american company GEOMETRICS.

The office has four  Ground Penetrating Radar systems, three of the Swedish company MALA and one of the Norwegian company 3d-Radar. These systems can perform two-dimensional and three dimensional imaging of the targets that are to be geophysically explored. The systems are:

1. The 3D-Radar GPR system. This system has pioneered next generation 3D Ground Penetrating Radar (3D GPR) using step frequency radar technology and innovative multi channel antenna design. The Antenna arrays  are:

• Model B1847, with continuous frequency coverage from 200MHz to 2.0GHz, 1.8 meter array length and 47 antennas elements.
• Model B1823, with continuous frequency coverage from 100MHz to 2.0GHz, 1.8 meter array length and 23 antennas elements.

For the processing and interpretation of GPR measurements the software used will be: Slice v.7, Examiner, Reflex and Reflex3D.

2. The Mala ProEx system (Professional Explorer) with its shielded antennas of 250MHz, 500MHz, 1000MHz, 1600MHz,  2300MHz and the RTA antennas  of 25-30MHz, 50MHz and 100MHz.

3. The GPR system GX HDR (Ground Explorer High Dynamic Range) with the shielded high frequency antennas of  the Swedish House of Mala Geoscience, the central frequencies of which are 80MHz, 160MHz, 450MHz and 750MHz. The geophysical instrumentation used (MALA GX system), built with HDR technology, delivers unprecedented data quality and performance. For the processing and interpretation of GPR measurements the software used will be: Slice v.7, Objectmapper, Geovision  and RADExplorer.

4. The Mala GPR Borehole, (Professional Explorer borehole logging system), with two pairs of optical (four-stranded) cables, 800m long each, and its un shielded borehole antennas of: 100MHz and 250MHz. measurement devices: Downhole και Crosshole.

For the processing and interpretation of the measurements the software used is: Radinter and Wintomo.

The depth of the geophysical exploration, depending on the antenna used and the conductivity of the subsoil ranges from 0.30cm up to 50m.

The office has the Geonics EM61 MK2 High Power system, which can detect metallic or non-metallic targets at depths of up to 8m, depending on their size.
