The invention discloses a
human body composition analyzer. The
human body composition analyzer comprises a detecting
electrode unit, a control device and an analysis device. The detection
electrode unit is connected with the control device which is connected with the analysis device. The detection
electrode unit makes contact with a
human body and is used for outputting measurement current and collecting a detection
signal, wherein the detection electrode unit can output measurement current at multiple frequencies. The control device is used for controlling the frequencies of the measurement current and receiving the detection
signal. The control device sends the detection
signal to the analysis device. The analysis device is used for analyzing the human
body composition on the basis of the detection signal. The human
body composition analyzer performs biological impedance measurement in a multi-frequency mode and can cover all frequencies needed for human
extracellular composition and human intercellular composition, a measurement result can be more accurate, the advantages that electrode end
contact impedance is eliminated, long-cable impedance is eliminated, and
body weight measurement accuracy is improved are achieved, and more accurate
living body composition data can be acquired.
