MRS 256 Micro Resistivity System

The MRS–256 Micro Resistivity System together with the processing method was designed for a detailed resistivity and self potential studies of measured areas , especially those of an Archeological interest .

The system of electrodes of a required array fixed e.g. to a wall of a building or simply to the ground is connected with the MRS-256 system that provides a measurement control .

The 3D model obtained after processing of the measured data allows distinguishing of crackles ,cavities and other various structures of walls or targets buried in ground .

The MRS-256 system consists of a Transmitter ans a Sensitive Receiver ( parallel 24 bit AD converters ) with the extremely high imput impedance

The MRS-256 is connected to the system of cable with electrodes in a array fit to the type of the survey .

The MRS-256 system is operated via RS232 cable from PC notebook ( not included ) .

The operating software is designed to be usefull in all real measurement conditions and offers :

Good visibility and distinction of the information on the screen
Easy , user.friendly operation with prompts
Current indication of parameters and results
Testing of impedance of electrodes .

The output data of the MRS-256 are compatible with special software 3D imaging and back projection developed for this purpose at the University of Palermo ( Italy ) .
