Soil resistivity is one of the main parameters to be considered in Cathodic protection design. Wenner 4 pin method is a well-known technique that is generally used in soil resistivity measurement. 4 pins are put in the ground with equal spacing (a) and the soil resistivity is calculated using following equations:

r = 2 p a R
r = Resistivity in Ω-cm
p = 3.14
a = Pin Spacing in cm
R = Resistance in Ω

Payesh Sanat Novin supply state of the art equipment which not only measure precise value of electrical resistivity, but also could transfer data to a Tablet or personal computer via Bluetooth.
