Frequency range

DC .... 50 kHz



Contact resistance

50 – 500 Ω (for normal soils)



Effective surface

2 cm2



DC potential

0.1 to 0.9 mV



Temperature Range


+5 to +40 °C



Temperature Drift

n μV/°C

the temperature drift of two electrodes in the current circle is much lower than n μV/°C because of the same electrical behaviour;

electrodes can be used at a wider outside temperature range if buried deep enough
