The soil resistivity kit equipment utilizes the four electrode method developed by the National Bureau of Standards known as the Wenner 4-pin Method. The test determines the average resistivity of the soil to a depth equal to the spacing between electrodes. Designed for the maximum pin spacing of 20 feet recommended for a standard survey.
The kit comes complete with the Soil Resistivity Reel with four color-coded lead wires harnessed together, four Heavy Duty Soil Pins, and a Soil Box with leads for laboratory testing, housed in a sturdy, foam-lined plastic case. Lead wires plug into the reel hub and terminate with spring-loaded clamps at the opposite end.
- Soil Resistivity Meter –Â NOT included with the kit, the HM-942 is sold separately
