seca mBCA Alpha vs Tanita BC-545
seca mBCA Alpha 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.
seca mBCA Alpha: when to consider it
mBCA Alpha is an eight-point BIA analyser using nine frequencies. Documentation lists a 24-second recording, 360 kg capacity and fat, skeletal-muscle mass and phase-angle outputs. The Alpha configuration contains the mBCA 554 platform and mBCA 545 handle.
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.
