Strengthen your diet and training regimen with a scale that accurately measures body fat, weight and hydration for a holistic analysis. This scale adopts advanced BIA (Bioelectrical Impedance Analysis) technology. BIA measures body hydration and body fat percentage by sending a safe, low-level electrical signal through the body. The signal is analyzed by the computer to determine the body fat and hydration percentages. It is more precise and provides more accuracy than traditional digital scale calculations. This scale uses high precision sensors to obtain more exact weight calculations as well.
