«Electrotest-TEM»
Purpose
Equipment «Electrotest-TEM» is intended for carrying out of field works by a method of becoming of an electromagnetic field in a near zone at carrying out of engineering-geological researches, geoecological and archeologic researches, searches of underground waters, and also deposits of firm minerals (nonferrous metals, bauxites, coal, etc.)
Scope
Definition of specific electric resistance and thickness of the layers composing a geoelectric cut, up to depth 300ě, construction of geoelectric cuts at engineering-geological and hydro-geological researches, the control over a condition of places of a burial place of industrial wastes, research of dynamics of penetration into an environment of liquid industrial wastes near to sediment bowls at carrying out of geoecological researches, searches of deposits of the firm minerals differing on specific electric resistance from breeds of the containing environment.
