Bodystat QuadScan 4000 vs Tanita BC-545

Bodystat QuadScan 4000 and Tanita BC-545: 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-545: when to consider it

BC-545 InnerScan is a body-composition scale with personal-profile memory. Its manual describes fat and muscle-mass results and graphs for tracking change. This is the original BC-545; specifications from later BC-545N or BC-545F models are not transferred.

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.
