Spares for Resistivity & Seismic

Non-polarizing electrode  is a device used to receive electrical signals in electrical exploration, and it is a special ground electrode for measuring potential difference.
The copper rod is placed in a bisque porcelain jar containing a saturated copper sulfate solution, and the copper rod is conductive through the ions of the copper sulfate solution infiltrated from the bisque porcelain jar. Such grounding conditions can reduce the polarization potential difference of the electrodes to within 1 millivolt, and also reduce the polarization potential difference of the measuring electrode itself, so it is called a non-polarized electrode.
