IGIS make - Model DDR3 - Resistivity Meters - Brochure

The DDR 3 Resistivity Meter is a specialized version of IGIS resistivity meters designed for use in resistivity surveys upto about 150m depth under geophysical favourable field conditions. It utilizes rechargeable batteries as power source to energize the ground thus eliminating the necessity of using the relatively expensive dry cells. The equipment consists of two separate comportments-one for reading the current (G.Unit) and the other for directly reading the resistance/the potential (P-Unit), both housed in a single box.
