Bodystat QuadScan 4000 vs InBody 970S

Bodystat QuadScan 4000 and InBody 970S: 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 970S: when to consider it

For a comprehensive consultation when you want to follow water distribution and phase angles alongside fat and muscle. This newer 970 generation offers detailed outputs for clinical, nutrition, sports and research settings.

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.
