InBody 520 vs seca mBCA Alpha
InBody 520 and seca mBCA Alpha: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.
InBody 520: when to consider it
An older model for following fat, muscle and water during nutrition or exercise changes, and for understanding past results. Includes ECW/TBW and lean-mass distribution across the arms, legs and trunk.
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.
