SCIP Tester

Sample Core IP Tester

The Sample Core IP Tester (SCIP) manufactured by Instrumentation GDD is an innovative way to measure the electrical properties of drill cores, samples and outcrops.

The SCIP is a portable, reliable, battery-operated instrument for evaluating the resistive properties and IP response of your cores. With this instrument, you get the information that a geophysicist needs to design an appropriate geophysical survey. In other words, you can know if an IP survey would be appropriate. The SCIP will also help you to better define your IP inversion.

Now, you can use your SCIP with your Android devices.




  • Apparent resistivity and time domain induced polarization (IP) measurement
  • User friendly and inexpensive
  • Versatile: use your own core holders
  • Transfers data from the PDA to your PC with an ISB cable
  • Screen decay curve (IP)
  • Provide real time feedback: direct calculation or resistivity and chargeability values
  • Applications : mining exploration and other related fields

Continuous improvement

A new optimized version of the core holder is now available including copper electrodes of larger diameter (85 mm instead of 50 mm).

In addition, new features have been added in the user interface offering new choice of time base (16, 32, 64 and 128 seconds) and a new output file compatible with Geosoft software.

All new SCIP Tester have these new features. Older models can be updated on request.
