The portable low-frequency electroprospecting generator - «ELECTROTEST-GS»

The low-frequency electroprospecting generator with the stabilized target current is intended for carrying out of engineering-geological researches, detection and procaking of underground industrial networks, revealing of a site of underground constructions and archeologic objects in pair with any convenient for application and working on frequency of the generator a measuring instrument.

Scope:

Definition of specific electric resistance of geoelectric sections by a method of resistance with installations of profiling and sounding;
Engineering-geological researches on working platforms;
Definition of characteristics of the ground on their electric conductivity under the bases of buildings and constructions;
Detection and procaking of water and sewer highways, underground pipelines, power{force} cables, lines of telephone and alarm communication, including a method of a charge;
Definition of a site of infringements of isolation of metal pipelines by registration of activity of corrosion processes;
Searches and allocation of archeologic objects.
