Electromagnetic Induction Ground Conductivity Meters

SPECIFICATIONS

• Provides measurement of both the quad-phase (conductivity) and in-phase (magnetic susceptibility) components within two distinct depth ranges, all simultaneously, without any requirement for soil-to-instrument contact.

• Maximum effective depth of exploration of 1.5 m, applications in agriculture, archaeology and general soil sciences.

• Includes two receiver coils, separated by 1 m and 0.5 m from the transmitter, providing data from effective depth ranges of 1.5 m and 0.75 m respectively when positioned in the vertical dipole orientation, and 0.75 m and 0.375 m respectively when in the horizontal dipole orientation.

• Coil technology, supported by temperature compensation circuitry, to improve temperature-related drift.

• Collapsible calibration stand to support automation of the instrument calibration procedure. Once positioned within the stand, the instrument is to be calibrated within seconds, without any requirement for iterative adjustments.

• Support both walking and trailer-mounted survey methods.

• External power sources to be connected to the instrument for extended field operations.

• Lightweight, rechargeable battery pack with 25 hours of continuous operation.

• Data collection is to be supported by the DAS70-AR Data Acquisition System, or other appropriate field computer, connected by either cable or Bluetooth wireless technology.
