Resistivity Measurement Data Sheet

Resistivity Measurement System

The resistivity measurement kit for Geocomp triaxial systems allows for laboratory determination of the minimum resistivity of a soil. Measuring soil resistance is key to determining corrosivity and how it can affect lifespan of underground structures.

Applicable Test Standards

  • ASTM G187
  • AASHTO T 288


  • Resistance readings with the push of a button
  • Available for triaxial test systems
  • Resistance measurements are unaffected by stray interference
  • Bluetooth ® compatible with PC or Android device for wireless data acquisition
  • Perform 10,000 readings on a set of replaceable batteries (D-Cell)
  • Data stored in XML format (or convert to spreadsheet) for easy reading by other applications


  • Measurement: Measured resistance and calculated resistivity values (expressed in units) are both stored per reading
  • Measurement Range: 0.01Ω to 10 MΩ (auto-ranging)
  • Accuracy: 0.01Ω to 1MΩ range ±1.6% ±1LS Display Digit ±0.01Ω; 1MΩ to 10MΩ range* ±5% ±1LS Display Digit
  • Sample Size: 2.0 in (50 mm) or 2.8 in (71 mm)
  • Dimensions: 10.5 x 12 x 5.75 in (267 x 305 x 146 mm)
  • Weight: 8.6 lb (3.9 kg)
