Bodystat QuadScan 4000 vs Tanita BC-418MA
Bodystat QuadScan 4000 and Tanita BC-418MA: 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-418MA: when to consider it
BC-418MA is a segmental body-composition analyser. An academic facility’s instrument description lists weight, body fat, fat-free mass and regional outputs. Check the exact device designation, including MA, when booking.

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.
