Soil Resistivity Test Equipment

Soil resistivity apparatus utilizes the Wenner 4-pin method developed by the National Bureau of Standards. The test determines average resistivity of the soils to a depth equal to the spacing between electrodes (pins). Analog or Digital Soil Resistivity Meters are available individually and selection of one is required for testing. A test kit is also available with the other components needed to perform the soil resistivity test.

• Soil Resistivity Meters in analog or digital models provide readings of soil resistance values. The analog model has 8 ranges from 0.1 Ohms to 1.1 Mega-Ohms. The digital unit has a total range of 0.01 Ohms to 10 Mega-Ohms, and is supplied with ProCP soil resistivity software. Both units are battery-operated and come with a NIST Traceable Certificate of Calibration.
• Soil Resistivity Test Kit includes components required for testing at the maximum pin spacing of 20ft (6.1m) recommended for a standard survey. The kit contains a soil resistivity reel with lead wires, soil pins, soil box for laboratory testing and carrying case which also holds the meter. The meter is purchased separately.
