Soil Resistivity - 4 Pin Wenner Method

Thank you for watching! Please Like and Subscribe! Conducting soil resistance measurements (ohms) and calculating soil resistivity (ohm-cm) utlizing the "4 Pin Wenner Method". This is a great tool/technique for cathodic protection technicians for mulitple purposes including cathodic protection design, troubleshooting and AC mitigation. Resistivity Formula = 191.5aR (feet) or 2πaR (centimeters) a=spacing R=resistance measured
