A multi-function portable bioelectrical impedance measuring instrument is provided that is easily held in the hand, and has its electrodes and its controls arranged to be easily manipulated. Embodiments include an instrument wherein a pair of electrodes is arranged on the back of a main body of the instrument such that they are both contacted by a user's palm when the main body is held in the palm of the hand. Another pair of electrodes, a set of operating switches, and a display are located on the face (i.e., the front) of the main body such that two fingers of the other hand of the user can touch the electrodes simultaneously and operate the instrument to obtain a body fat occupancy ratio and/or pulse rate based on the impedance measured by the electrodes. A photoelectric detector is also provided on the face of the main body to produce a signal to provide a blood pressure reading or pulse rate. Since the electrodes can be firmly held in contact with the user's skin due to their ergonomic arrangement, the instrument is easily operated and produces accurate monitoring of body fat occupancy ratio, pulse rate, blood pressure, and the like.
