I. Applications
Downhole Resistivity Cable is specially designed for VES,ERT, IP and SP electrical resistivity in water, shallow sea and borehole well. The applications for marine resistivity cable are including but not limited to Bedrock depth detection, bedrock topography, fracture and fault identification, cavity detection and mapping, ores and mineral deposits, geology, soil type or bedrock type/bedrock change, groundwater aquifers, groundwater contamination, saltwater intrusion, waste and pollutant mapping, etc.
- Specially designed encapsulated vulcanization stainless steel electrode for underwater applications.
- Lighter weight but maintaining the same low noise level.
- Robust design cable with strong mechanical strength, Kevlar fiber added and good insulation performance.
- Compatible with all main stream resistivity meter, resistivity system and devices: ABEM, ARES, GDD, IRIS SYSCAL PRO, PASI RM1 Earth Resistivity Meter and etc.
- 10-electrodes,11-electrodes,12-electrodes,16-electrodes, 18-electrodes, 21-electrodes, 24-electrodes, 28-electrodes, 30-electrodes, 32-electrodes, 42-electrodes, 48-electrodes, or 56-electodes are optional.
- Customized electrode numbering, section size, take-out type and spacing is available upon requests.
