Fabrication of resistivity meter and its evaluation

Abstract

This paper reports the fabrication of a resistivity meter. The device was designed to measure potential values while the current was kept constant. Through this, the resistivity of the soil was obtained. The device was tested in the Federal Polytechnic, Ede, Nigeria , using Wenner four- electrode point arrangement and the result obtained was not far from the values gotten using standard tetrameter under the same conditions.
