Multipurpose Data Logger

GEODATALOG 8  is a multipurpose data logger which works directly connected to a PC. Data are automatically transferred to the PC in real time for live monitoring of the tests progress.

GEODATALOG 8 records and monitors in real time the measurements requested for soil mechanics testing, as: consolidation, shear, triaxial, permability and many others.

It is compatible with strain gauge load cells, pressure transducers, linear LDT transducers, LVDT conditioned transducers, potentiometric displacement transducers.

GEODATALOG 8 is conceived with a modular and flexible concept: up to 8 instruments can form a network and then create a modular system with up to 64 independent channels.

The data acquisition unit is supplied complete with general purpose  DATACOMM 2 PC software for fully comprehensive data management of both GEDOTALOG 8 and HYDROMATIC.

DATACOMM 2 software combines  the active channels into customizable groups by the operator. Data acquisition for each group is an independent task which can be started/stopped automatically with specific acquisition and logging mode.

Software allows remote calibration of the connected sensors up to 10 points with polynomial fitting curve up to eight degree.

ASCII  format data export is available for combination with our geotechnical Geo-Analysis-Templates suitable for post-processing and printout of test certificates according to the most important international Standards.
