Non polarizing electrodes are mainly used in following geoelectrical applications:
- Induced polarization
- Spontaneous potentials
- Downtown measurements
By means of electrodes, potentials generated by electrochemical action between electrode and ground are eliminated, in order to reduce contact resistance.
- DC potential: a few mV (shortly after manufacturing)
- Contact+internal resistance of a couplet: 30-300 Ohm (for normal ground)
- Surface of the bottom: 58 cm2
- Mass: about 1 kg
- Diameter (D): 90 mm
- Height (H): 80 mm
