Description

This kit is designed for use with the new Miller 400A and Miller 400D Resistance Meters, however it ships with a foam insert that allows it to store the Nilsson 400 meter, if desired.

The Soil Resistivity Test Kit is designed to conveniently store and carry all of the equipment required to calculate the resistivity of soil. The equipment provided, when combined with a resistance meter (such as the Miller 400A or Miller 400D – each sold separately), is all that is necessary to perform the Wenner Four-Pin Method, as outlined by the ASTM G 57-06 Standard, as well as the Soil-Box Method.

The M. C. Miller 4-Pin Test Reel, shown below, has been designed and engineered to be used in conjunction with any one of MCM’s multi-meters, the Miller 400A or Miller 400D Resistance Meters, or similar four-terminal soil test instrument.

The test setup utilizes the mechanics of the “Four Electrode Method,” which was developed by the National Bureau of Standards and is commonly known as the Wenner 4-pin Method. The resultant resistivity is the average resistivity of the soil (electrolyte) to a depth equal to the spacing between adjacent electrodes (soil pins). The maximum depth (pin spacing) of this standard test set has been designed for 20 feet, which is recommended for standard survey.

The Soil Resistivity Reel is made up of four (4) separate, color-coded lead wires of: 5-foot (yellow), 25-foot (orange), 45-foot (red) and 65-foot (black) lengths. Lead wires are harnessed together and mounted on a lightweight handheld reel. Wire ends at the reel are affixed to female banana plug jacks (mounted in the center hub area) while the opposite ends are terminated with Mueller 27-C clips. Two-foot, color-coded, jumper leads with banana plug ends are supplied with soil resistivity reel to facilitate connection between the REEL and the test meter.

All lead wires and jumpers are made of No. 16 AWG, 105 strand copper wire with PVC insulation. In addition to color coding of the wires, all ends are clearly labeled as to their connection point.
