A6000SE  GEOELECTRICAL PROSPECTIVE

MAE A6000SE modular combined system is a very compact and versatile equipment for 24-channel/24-bit active and passive seismic PROSPECTIVEs, and geoelectrical PROSPECTIVEs using both the four-terminal network technique or the multi-electrode electrical tomography system.
The seismic or geoelectrical survey methods are easily selected from the main menu of a touch-screen colour display. Upon choosing the data acquisition system needed (single measurement or complete cycle), data retrieval is automatically performed by the push of one button.
This seismograph main characteristic is the real 24-bit resolution for each single channel; this is achieved thanks to MAE new 24-bit data acquisition card, which uses an A/D 24-bit digital converter for each of the seismograph entry channels. This peculiar characteristic makes the A6000SE seismograph the ideal solution for any active or passive seismic PROSPECTIVE, structural surveying and inspections of buildings and infrastructure facilities (acquisition of vibrations by accelerometers or low frequency seismic sensors, tomographic surveys).
