Using This Equipment

For more information and to utilize this equipment, please contact Andrew Nyblade.

Equipment full name: Syscal Pro Switch 48 Resistivity

Description

The ERI is an all-in-one multi-node resistivity and induction polarization imaging system. The Pro offers a maximum 1,000V transmitting pulse (2,000V peak to peak), at up to 2.5A, for a total of 250W of transmitting power. The multi-electrode imaging system supports up to 120 electrodes on a single line at 10m spacing.

Features

  • A 10-channel resistivity meter
  • Allows for simultaneously obtaining a set of 10 measurements and performs automatic switching of the electrodes
  • Equipped with software that allows the user to:
  • Create 2D/3D-surface/borehole measurement sequences
  • Create some sequences of measurements, manually or automatically (with an estimated maximum investigation depth specified by the user)
  • A specific mode that allows for continuous logging, specially designed for marine applications

Example Applications

  • Groundwater mapping
  • Fresh/saltwater contact determination
  • Depth to bedrock measurements
  • Thickness of bedrock alterations
  • Aquifer layers- determination of depth and thickness
  • Pollution monitoring (Jeremy, not sure what pollution monitoring means??)
  • Location and imaging of buried structures
  • Detection and characterization of sub-surface cavities
  • Geotechnical applications-detection/location of clayey layers

Rental Cost includes:

  • Written standard operating procedures
  • Training on use, calibration, and maintenance as appropriate (as needed-depends on length of rental period)
