The seca mBCA 515 is a medical Body Composition Analyzer, which is ideally adapted to the working conditions in hospitals and medical practices. After all, in order to obtain a truly meaningful Bioelectrical Impedance Analysis (BIA), we need to look beyond the many technical requirements. A faster and simpler way to ascertain body composition, e.g., body fat and water, also has to be ensured. For another, the measurement results have to be reproducible under normal clinical working conditions.
