Bodystat QuadScan 4000 vs Tanita BC-601
Bodystat QuadScan 4000 and Tanita BC-601: 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.
Tanita BC-601: when to consider it
BC-601 is a segmental scale for tracking fat and muscle mass in five body regions. Its display sits on a pull-up handle and results can be stored on an SD card. Weight capacity is 150 kg; consistent preparation and interpretation matter when comparing changes.

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.
