JDX-2Dr 500M 1000M 3000M Water Well Gamma Probe Borehole Logger
JDX-2Dr Natural Gamma & Electrical Resistivity probe
Description
The Electrical Resistivity Probe concurrently measures natural gamma radiation, gradient resistivity, normal resistivity, and spontaneous potential (SP). This multifunctional tool allows users to record resistivity profiles at various investigation depths, providing valuable insights into permeability, porosity, water quality, and the characteristics of geological formations.
