OKM FS-Thermoscan Cavity Detector

OKM FS-Thermoscan Cavity Detector

Thermography and cavity detection

All of our metal detectors and geophysical detecting instruments are part of the "FS - Future Series", a line of our latest technology to detect buried objects and underground structures. Beside the measuring instruments it includes our 3D software which assures a detailed analysis of the measured results.

FS-Thermoscan is a measuring device to detect differences in temperatures of the environment. So it can identify cold and warm areas of a field and conclusions concerning hidden objects and structures are possible. FS-Thermoscan is usable as a stand-alone device or can be connected to the Earth Imager eXp 4000 and eXp 5000. In that way it is even possible to get 3d graphics out of the measure values.

Possible applications are

  • the detection of cavities (caves, tunnels, chambers, chests, ...),
  • the visualization of the distribution of temperatures as well as
  • the measurement if differences in temperatures.

The FS-Thermoscan stands up for its usage and compact design. Create high resolution 3d graphics of the underground by measuring the differences in temperature on the surface of the ground.

Because of the integrated laser pointer pinpointed measurements are possible. The device works contactless and therefore a field can also be researched from far distances. This is an important advantage if the field is impassable by the searcher.
