JJH-2 Resistivity 1～4000Ωm Accuracy 2% ±1Ωm Polarization 1~100% Electronic Polarization

Description

The JJH-2 Electronic Polarization probe measures 16” & 64”Normal Resistivity,Spontaneous Potential (SP),16” & 64”Polarization. A high chargeability response is an indication of the presence of metallic sulphides and oxides or cation-rich clays. Users can log resistivity profiles with different depths of investigation and gain information about permeability, porosity, water quality and geological formation properties.

Operating Conditions:Uncased；Borehole Fluid:Water or Mud

Features & Benefits

1. Measuring electrode is the non-magnetic alloy, electrostatic shielding technology, special ways of excitation.
