Special Skin Electrodes for Bio-Impedance Testing
Precise and reliably reproducible results in bio-impedance testing can only be achieved when specially suited BIA electrodes are used.
Each two adhesive electrodes are placed on hand and foot of one body side. Before electrode placement the skin must be cleaned by applying a suitable, alcoholic, non-irritable swap or spray, removing fatty substances and skin residue.
While a non-susceptible constant current is entered into the body by the “injecting” electrode pair, the second pair senses the drop in voltage and determines Impedance Z, the body dependent total resistance.
The exact placement of electrodes (PDF: 745,82 KBytes) is illustrated and practiced as part of our BIA seminars. Only the anatomically correct position of electrodes will lead to correct and reproducible bio-impedance results!
