X-ray CT Scanner

X-ray CT Scanner

The X-ray CT scanner three-dimensionally analyzes the fault structure, sedimentary structure, etc. of core samples without destroying them. By applying medical X-ray CT scan techniques, X-ray see-through images and computer tomography (CT) images can be generated.

Multi Sensor Core Logger

Multi Sensor Core Logger

The multi-sensor core logger has been developed to measure the physical properties of core samples without destruction. By moving a core sample past sensors using a conveyor belt-like mechanism, it is possible to continuously acquire physical property data, density, P-wave propagation velocity, magnetic susceptibility, electrical resistivity, etc.

Color Spectrophotometer Sensor System

Color Spectrophotometer Sensor System

Mounted with a color spectrophotometer sensor system, the XYZ-MSCL continuously acquires color spectrum data from core sample sections. With core samples placed side by side and sample length and measurement interval data input, the sensor determines the distance between it and the core surface using laser light and makes measurements while moving horizontally and vertically.
