MEASUREMENTS
Body weight, body fat, body water, muscle mass, BMI (body mass index), BMR
(kcal), bone mass and visceral fat.
WORKING THEORY
This device is based on the BIA (Bioelectrical Impedance Analysis) technology. To
measure body bioelectrical impedance, it makes the results much more accurate
with new measuring technology. The reason is human body fat is not conductive,
however muscle and water are good conductors. This device measures
bioelectrical impedance to calculate the composition of human body.
