Earth resistivity measurement instrument
WebThe Sonel MRU-200-GPS earth resistance and soil resistivity meter is a versatile meter for earth resistance and soil resistivity measurements. The device allows the use of all known earth resistance measurement methods. This renders it an unrivalled measuring instrument in its category and definitely makes it stand out from other devices of its ... Webρ = soil resistivity in Ohm meters (assuming a uniform soil). L = length of electrode buried in soil in meters. A = area in square meters. From the above, if the soil resistivity is known then the theoretical resistance of a single vertically driven earth rod can be approximately calculated using the formula below. Where:
