ABSTRACT
A simple resistivity meter was designed and constructed using cheap and locally available electronic components which included two reversing switches (DPDT), 500W “modified” sine wave inverter, a bridge rectifier, 2.2 12V DC car battery used as the power source. The data/result obtained using the constructed resistivity meter was quite comparable with that of the ABEM terrameter LS 200 for a current electrode spread of 70m of the ABEM terrameter LS 200 ranges from 613.82 while that of the simple resistivity meter ranges from 664.34 shallow investigations with depth of penetration at lest different from that of the standard meter at deeper depth of penetration. Efforts are being made to improve on the performance of the simple resistivity meter.
