Terrameter LS Resistivity Meter from GISCO

Imaging system measuring Resistivity, IP and SP.
High reliability, safety, and robustness under harsh field conditions.
Easy to use with multi-lingual graphical user interface on sunlight-readable color LCD.
On-site capabilities for data QA, system diagnostics and fault tolerance
Superior quality in data acquisition with powerful transmitter and high dynamic range multi-channel receiver.
Open communication platform for data exchange, Internet and remote diagnostics (TCP/IP, USB).

Terrameter LS is controlled using the incorporated Firmware. It has a Graphical User Interface that is easy to follow in all its aspects. Clear and instructive graphics assists the user in the operation of the instrument.
For enhanced Data Quality Control in the field it is possible to display the measured Multi-Electrode Resistivity Imaging data in near real time as a pseudo section.
