seca mBCA Alpha vs Tanita RD-545HR
seca mBCA Alpha and Tanita RD-545HR: 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 RD-545HR: when to consider it
RD-545HR uses dual-frequency segmental BIA with a handle and app connection. It provides fat, muscle and regional results as well as heart rate. HR distinguishes it from the original RD-545; a scale’s bone-mass estimate is distinct from bone densitometry.

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.
