GD-10 Electrical Resistivity Meter

GD-10 Electrical Accessories

GD-10 is developed based on the latest digital and analog circuitry technique, making it the world leading multi-functional direct current (DC) method instrument.Geomative integrated   the advantages from both conventional centralized cabling system and distributed cabling system. We combine the low cost and high reliability from the former and the high efficiency with infinite expand-ability of the cable from the latter system. So a sectional centralized ERT technique is established by Geomative, which attained both the rapidness of distributed cabling and the reliability of centralized cabling.

Features:

  • Resistivity automatic stacking and support single point
  • Flexible, efficient and convenient wiring
  • Plenty of arrays and custom scripts
  • Multi-dimensional data display
  • The unique segmented centralized mode of GD-10 system
  • Automatic stacking to improve data quality

GD-20 Electrical Resistivity Meter

GD-20 Electrical Accessories

GD-20 is a brand-new multi-channel electrical method system, independent 5/12 channel design, It can measure up to 10 points at the same time, greatly improving the efficiency on site. GD20 can be used for self-electricity, apparent resistivity and IP testing. Compared with single-channel equipment, the multi-channel average test efficiency is increased by 2-3 times, greatly shortening the field construction period.

The GD-20 system is portable and has its own memory to store data. Multi-channel conversion box  Supporting VES, ERT, and N-∞ settings. VES can test 12 sets of sounding points in the meantime , ERT test can meets 10-channel data acquisition, N-∞ gear meets the application of N-connected infinity device, and independent 10-channel design maximizes test efficiency.

Features:

  • Complete DC solution
  • Supporting Resistivity automatic iteration and single point testing, can improve data quality and testing efficiency
  • Flexible, efficient and convenient layout, double connection method can twice enlarge the current threshold
  • Powerful and efficient rolling and 3D testing and pseudo 3D scanning
  • Rich devices and support custom scripts
  • Multi-dimensional data display, all problems, on-site discovery, real-time positioning
