When you stand on our Tanita monitor, a very low, safe electrical signal is sent from four metal electrodes through your feet to your legs and abdomen. In segmental models, the four hand-held electrodes will provide extra readings for each leg, arm and abdominal area.
The electrical signal passes quickly through water that present in hydrated muscle tissue but meets resistance when it hits fat tissue. This resistance, known as impedance, is measured and input into scientifically validated equations to calculate body composition measurements. Depending on the monitor, body composition measurements are provided in under 20 seconds.
