ERT cables for ABEM instruments are multi-electrode cables which are used to transfer current and potential signals from resistivity meter to the ground, which is mostly widely used in electrical resistivity tomography(ERT, Electrical Imaging) method and resistivity imaging method for infrastructure projects, environmental studies, water content variations, movements of pollutants and seepage through embankment dams etc.
- Suitable for Terrameter LUND(4,8 or 12 channel) resistivity& IP instrument and other ABEM instruments.
- The ERT cable could be 10 take-outs, 11 take-outs, 21 take-outs, 24 take-outs or 32 take-outs which will be depended on client's applications.
- Standard electrode spacing is 0.5m, 2m, 5m, 10m, 15m or 20m but customized distance between electrode take-outs(spacing) could be defined by the client.
- Connector type is ITT Cannon KPT06F18-32P or equivalent 32 pin male connector with dust cap equipped.
- Cable electrode is molded take-out with colors of red and blue alternatively.
- Cable jumpers which are used to connect steel electrodes to imaging cable's electrode take-outs are also optional.
