Description

GF Instrument’s CMD Mini Explorer electromagnetic conductivity meter is designed for survey depth ranges from 0.3 to 1.6 m. The system uses a contactless method allowing fast measurements of conductivity and inphase under all field conditions (including very dry and icy ground). The Mini 6L probe is equipped with 6 receivers with excellent temperature stability. This way makes for high resolution depth graded mapping as well as imaging of sections possible and useful for wide range of walking and moving applications.

 

CMD-MiniExplorer 6L

…with simultaneous 0.3 m, 0.5 m, 0.8 m, 1.1 m, 1.6 m, 2.3 m full depth ranges is designed for high resolution investigation of shallow layered structures in the frame of:
agriculture, forestry, archaeology, criminology, road inspection and civil engineering.

CMD-MiniExplorer 6L: SIX-depth probe
…with depth ranges:
0.3 / 0.15 m, 0.5 / 0.25 m, 0.8 / 0.4 m,1.1 / 0.5 m, 1.6 / 0.8 m, 2.3 / 1.1 m
for high resolution mapping and section imaging.

Control Unit:
  • Connection with probe is provided by cable or Bluetooth unit.
  • Five modes of measurements:
    • Manual measurement – the user starts measurement at each point by pressing the key or by probe button. The point position is updated automatically in the preset grid or can be entered directly. Each point can be re-measured or skipped and completed with a comment.
    • Continuous measurement – data are measured and saved continuously in chosen measuring period. The positions on the profile are determined by length marks with consequent recalculation of positions of individual readings.
    • GPS Manual measurement – the user starts measurement at each point by pressing the key or by probe button. The position is determined by GPS receiver.
    • GPS Continuous measurement – data are measured and saved continuously in chosen measuring period. The position is determined by GPS receiver.
    • Search mode – data are measured continuously but are not saved.
  • Map preview of measured area (up to 15000 positions).
  • In-situ 1D inversion (two-layered model).
  • Two integrated Bluetooth channels.
  • Detachable GPS receiver (UTM/UPS recalculation possible).
  • USB data transfer or direct saving on USB flash disk.
  • Factory and user calibrations (stored in the probe).
  • Measurement time: 0.1 – 20 s.
  • 128 MB data flash memory:
    • max. 64 files.
    • max. 4.8 millions measured points.
  • Graphical B/W or colour display with backlight.
  • Real-time clock.
  • Power supply:
    • Rechargeable Li-Ion battery.
    • Supplementary 6 AA batteries (single-use or rechargeable NiCd or NiMh).
