Magnetic Susceptibility Tool

The Magnetic Susceptibility Tool is a specialised instrument equipped with a two- or three-coil sonde, designed to measure the apparent magnetic susceptibility of subsurface formations.

The three-coil configuration enables accurate measurements across a wide range of geological conditions, while the dual spacing feature allows for investigation of both borehole and formation fluid properties.

  • Wide Range Measurement: Suitable for diverse formations with varying magnetic properties.
  • Dual Spacing Capability: Facilitates detailed analysis of borehole and fluid characteristics.
  • High Sensitivity: Provides precise magnetic susceptibility readings.
  • Dimensions: 1.2m (length) x 45mm (diameter)
  • Weight: 5kg
  • Apparent Susceptibility Range: 10⁻⁵ – 0.5 S.I. Units
  • Resolution: 1 count
  • Transmitter Coil Frequency: 2kHz


  • Minimum Diameter: 50mm
  • Environment: Suitable for dry or fluid-filled boreholes
  • Lining: Compatible with unlined or plastic-lined boreholes

The Magnetic Susceptibility Tool is an essential instrument for evaluating the magnetic properties of subsurface formations. Its advanced design ensures accurate and reliable results, making it ideal for geological, geotechnical, and environmental investigations.
