EFP-06
default electrode for MT measurements
The EFP-06 is the default electrode for MT measurements.
The lifetime depends on the usage.
E.g. a replacement after 18-24 months is recommended.
When this type of electrode is already "much too old" you see high static offset and high noise in your time series.
A more detailed description can be found on Dr. Simon Andras's homepage.
Technical data
| Frequency range | DC .... 100 kHz |
| Contact resistance | 50 – 500 Ω (for normal soils) |
| Effective surface | 27 cm2 |
| DC potential | a few mV |
| Temperature Range | +5 to +50 °C |
| Temperature Drift | -0.1 mV/°C [-10° - +50° C] the temperature drift of two electrodes in the current circle is much lower than -0.1 mV/°C because of the same electrical behaviour; electrodes can be used at a wider outside temperature range if buried deep enough |
| Weight | appr. 0.7 kg |
| 12 - 16 months; careful usage | length 117 mm, diameter 64 mm |
