Bodystat QuadScan 4000 vs InBody 120
Bodystat QuadScan 4000 and InBody 120: 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 120: when to consider it
InBody120 is useful for following fat and muscle while changing your diet or activity. A meaningful consultation benefits from the full computer-generated report; the small display shows only part of the results.

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.
