Nonpolarizing electrodes are used in geoelectrical and electromagnetic surveying especially in magnetotelluric (MT), resistivity, induced polarization (IP) and spontaneous potential (SP) measurements.

Our nonpolarizing electrodes are compatible with all receiver instruments including ADU (Metronix Geophysics), MTU (Phoenix Geophysics), ZEN (Zonge International), Syscal (IRIS Instruments), etc.

Main features

Self (DC) potential of a couple: a few mV (shortly after manufacture)
Contact+internal resistance of a couple: 100-300 Ohm (shortly after manufacture, on normal ground)
Surface of the bottom: 58 cm2
Mass: about 0,8 kg
Diameter (D): 90 mm
Height (H): 80 mm
