Geologger-GWS 3i & GW Combination Probe

The Geologger GWS3i is a combined logging system that enables simultaneous measurements of three items: natural gamma, electric logging (16" and 64") and spontaneous potential by connecting it to the GW Combination Probe (Model-3493).

After excavation, by inserting a GW Combination Probe into the borehole and moving it up and down, the ground characteristics at various depths can be obtained.
