GS6.5 Human body composition analyzer can detect various components of human body and analyze human health status, which applies the accurate measurement of AVR micro computer controller, bases on new statistics method DXA, to analyze human elements: fat, weight, BMI, non-fat and other health indicators through multi-frequency bioelectrical impedance analysis scientific basis for losing weight effectively. Which is considered as an epoch-making results of the health industry. It is healthy for each test, thus develop new treatments analysis of health data to lose weight.
