Used to calculate body composition (water, fat tissue, cell mass) and basal metabolic rate. By using a relatively simple device, the electrical resistance (body cell mass = good conductor, fat tissue = bad conductor) and capacitive resistance (created at the cell membranes of the cell mass) is measured and used to calculate impedance. Further calculations are made using empirically developed algorithms. ...
