The survey meter, developed by researchers of the Meari Sounder Company and Kim Chaek University of Technology, is an advanced technological equipment for prospecting useful minerals, underground water and geothermal resources on the basis of analyzing values gained from far-infrared detection and self-potential measurement.

This can be used for various purposes of survey. The equipment, easy to carry, ensures high prospecting speed and efficiency and displays through three-dimensional image the results of simultaneous measurement on outcrop and deep ore body.

With the help of the survey meter, new fields of useful minerals have been founded in recent years.
