GRG, Georhythmogram, Skin Resistance Measurement According to Dr. Hartmann
The process of skin resistance measurements according to the Dr. Hartmann is a reliable method for the detection of biological effects of geopathogenic zones (water veins, faults, grids), technical domestic installation and building materials to humans.
Also the effect of drugs or other objects (gems, jewelery etc.) on a person can be judged by this method.
The preparation of a geo-rhythmogram according to Dr. Hartmann is a possibility for verification of e.g. the sleeping area situation. Here, the body regulation is determined through measurement of the skin resistance.
The body regulation does not calm down at geopathogenic places and within the sphere of influence of electro-stress or other stressing factors, while at neutral places it is balanced and calms down slowly.
The test subject is located at different places or is exposed to different (stress causing or stress reducing) influences. The resistance values are determined in each case between both hands in 30 second time intervals.
The hand-held probes consist of a special brass alloy.
