  • The device uses Bioelectrical Impedance Analysis through four contact electrodes to measure the body composition.
    The device sends a minute electric signal through the body, an electric current flows in accordance with the electric conductivity of high water depending on the amount of body water, fat cells, muscle cells and skin cells.
    Alternatively, resistance occurs, this resistance is generated at the time it contacts body components.
