Spacer parts for the measurement of spectral induced polarization at the laboratory scale

• Spectral induced polarization (SIP) is an electrical method used in geophysics.
• For a depth dependent measurement the spacing of the electrodes has to be varied.
• Here we have some combine able parts which allow to perform measurements on the laboratory scale.
• Especially the hole diameters depend on the measurement device and the printer they are produced with. (most probably they have to be adjusted for the individual situation)
• constructed and produced in collaboration with Martin Sonntag

OpenSCAD construction files and documentation

The OpenSCAD files to construct such parts and some more documentation on how to perform such measurements can be found on github at:

• https://github.com/gnibeil/SIP-spacers

Parts

• There are three types:
  • small holes in the middle, and large at the border
  • only small holes
  • only large holes
  • can be combined as needed
  • hole size should be checked with your measurement equipment
