The innovative diagnostic instrument is the only Body Composition Analyzer (BCA) which makes precise medical measurements and analyzes and interprets the BCA raw data against medical reference values. The results help doctors to detect early signs of disease and to keep a close watch on treatment progress. The seca medical Body Composition Analyzer 515/514 (seca mBCA) is ideally adapted to the working conditions in hospitals, medical practices and rehabilitation facilities to determine the exact body composition of individual patients. Electrical impedance is measured via electrodes to determine fat, muscle and water components.
