How Do Body Fat Scales Work? By sending a safe, low-level electrical current through the body and measuring the rate at which the electrical current travels through the body, the body composition is determined. Wyze Scale uses four independent floor sensors that measure to the 10th of a pound. This basically means the scale can measure how much our bodies resist an electrical pulse.

Most research shows that body fat scales aren’t accurate at tracking individual changes in body composition over time. The vast majority of body fat scales use ‘bioelectrical impedance analysis’ (BIA) to read your results. Salter Body Analyser Scales use BIA (Bio Impedance Analysis) technology which passes a tiny electrical impulse through the body to determine fat from lean tissue, the electrical impulse cannot be felt and is perfectly safe.
