About

Various remote connection options eg dial up modem

Supporting vibrating wire sensors the new dataTaker® DT8xG GeoLogger is ideal for all geotechnical data logging applications. The dataTaker® GeoLoggers have built-in vibrating wire support providing ideal data acquisition and monitoring solution for the engineer working in the geotechnical environment.

The dataTaker® GeoLoggers can monitor a wide variety of geotechnical datalogging applications including slope stability, subsidence, dam wall monitoring, tunnel and mining excavation, ground water, tunnel wall monitoring and site assessment.

The DT80G and DT85G can be expanded simply by connecting dataTaker® Channel Expansion Modules (CEM20) to provide 100 to 300 vibrating wire channels with thermistors.

The advanced new dataTaker DT8xG range of GeoLoggers are compatible with all major brands of geotechnical instrumentation including Slope Indicator, RST Instruments, Geokon, Soil Instruments, Roctest, AGI - Applied Geomechanics Inc.
