The present invention provides a multifunction health device, which comprises a meter and a platform. The meter has two electrodes arranged separately at its two sides or both arranged at its one side, and the meter has another electrode arranged in its bottom. The platform has four electrodes arranged in its top face, and a pressure sensor arranged in its inside. With or without some parts assisting, the single use of the meter can function as an ECG detector, a TENS machine, a thermometer, and a first sphygmomanometer. Connecting with the platform, the meter and the platform can function as an ECG detector, a weight scale, and a body composition estimator. Further, the meter can alternatively connect with a chassis thus functioning as a second sphygmomanometer, a stethoscope, a glucose meter, or a pulse oximeter.
