Patient health is monitored by invasive as well as non-invasive methods. As invasive methods are harmful to patient's body medical science requires more non-invasive methods. Bioimpedance spectroscopy (BIS) provides information regarding patient health in clinics as well as in home noninvasively. This paper describes design and implementation of the Bioimpedance Spectrometer. It uses magnitude ratio and phase difference detection method as basic technique. Developed bioimpedance spectrometer measures impedance in the 10 KHz to 1 MHz range of frequency which is β-dispersion range. Pathological changes generally occurs in this range.
