Sample Core IP Tester
The Sample Core IP Tester (SCIP) manufactured by Instrumentation GDD Inc. 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.
Features:
- 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
Now, you can use your SCIP with your Android devices.
