is designed for rock apparent resistivity in-situ measurement via through-rock current transmission and rock resistivity electrosensitive recording, as well as for GR exposure rate measurement (0.03 – 3 MeV). The tool can also be used to measure rock spontaneous polarization.
The tool is used with one-core and three-core cable.
