Model QL40-ELOG - Electrical Resistivity Borehole Probes

The QL40-ELOG digital probe measures 8, 16, 32 and 64 inch normal resistivity, single point resistance (SPR) and spontaneous potential (SP) simultaneously. Users can log resistivity profiles with different depths of investigation and gain information about permeability, porosity, water quality and geological formation properties.
