Description
Soil resistivity is a measure of how much the soil resists the flow of electricity. It is a critical factor in design of systems which rely on current passing through the Earth’s surface. Soil Resistivity testing measures the resistance of soil. Soil resistivity testing generally requires a combination of the following components:
- Soil resistivity test instrument
- Metal pins
- Wiring
- Probe with two isolated electrodes
- AC or DC current source
- Ammeter and volt meter
- Soil box
Equipment necessary to perform a soil resistivity testing depends on the soil resistivity method selected for the survey. Typical methods of measuring soil resistivity are as follows:
- Wenner 4-Pin
- Single Probe
- Soil Box
