Soil Resistivity Test Equipment

Soil resistivity testing equipment 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). Digital or Analog Soil Resistivity Meters are available separately. Selection of one is required for testing. A test kit with the other components needed for soil resistivity measurements is also available. Testing with the Wenner 4-pin method meets ASTM G57 and AASHTO T 288 standards.

  • Soil Resistivity Meters are used with the HM-940 Soil Resistivity Kit to determine soil resistance values. Meters are available in analog or digital models. The analog model has 8 ranges from 0.1 Ohms to 1.1 Mega-Ohms and operates with C cell batteries. The digital unit has a total range from 0.01 Ohms to 10 Mega-Ohms and comes with ProCP soil resistivity software. It uses D cell batteries. Both models come with a NIST Traceable Certificate of Calibration. They are each also equipped with a weatherproof carrying case to conveniently store and carry the meter and components.
  • Soil Resistivity Test Kit includes components required for determining resistivity of soil. The test kit is designed for the maximum pin spacing of 20ft (6.1m) recommended for a standard survey. The kit contains a soil resistivity reel, soil box with test lead wires, and soil pins. A sturdy plastic case conveniently stores and carries kit components.
