WebSep 28, 2024 · Chemical rods are suitable for high resistivity soils — rock, mountain tops, sandy soil — and places with excessively high or low temperatures. This type of rod is a tube filled with mineral salts distributed evenly. It has holes along its length, allowing the entry of soil moisture. The moisture combines with the salts and dissolves them. WebTo measure the soil resistivity start the Fluke 1625 and read the resistance value in ohms. In this case assume the resistance reading is 100 ohms. So, in this case we know: A = 3 meters, and. R = 100 ohms. Then the soil resistivity would equal: r= 2 x p x A x R. r = 2 x 3.1416 x 3 meters x 100 ohms.
