Large Size Blue Backlight LCD Body Fat Scale Bluetooth Function

Large size Blue Backlight LCD Body Fat Scale With Bluetooth Function 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 that human body fat can not be conductive, but muscle and water are good conductors. The device measures human body bioelectrical impedance to calculate the composition of human body. Features
