Bodystat QuadScan 4000 vs InBody 970
Bodystat QuadScan 4000 and InBody 970: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.
Bodystat QuadScan 4000: when to consider it
QuadScan 4000 measures impedance at four frequencies using adhesive electrodes. Alongside estimated fat and fat-free mass, it reports body-water compartments, resistance, reactance and phase angle. Testing is supine; the operator enters height and weight.
InBody 970: when to consider it
InBody 970/970S is a professional series for segmental body-composition analysis, including body water and phase angle. The variants differ in frequencies and testing time; location details identify the exact model.

Fat-free mass is not pure muscle mass. A single result is not a diagnosis. Different devices and similarly named metrics may use definitions that are not interchangeable.
