Inbody uses multiple frequencies in its measurements
MultiFrequencyControlling the path of high frequency waves is very difficult. This technical know-how is an InBody specific specialty and has been accumulated over many years of experience in the field.
Electric current has a different penetration force depending on frequency. Low frequencies travel down the flow of the external surface water and are unable to penetrate the cell wall, thus measuring the water content outside of the cell. A higher frequency will measure the water content inside of the cell because it penetrates the cell wall. By using a diverse set of frequencies, the InBody can measure water contents inside and outside the cell separately.
Also, with the usage of several different frequencies, you are able to provide more information on the body composition because more resistance values are attained. The InBody720 is based on six different frequencies that measure each segment, providing a total of 30 separate impedance values.
