InBody R20 vs seca mBCA Alpha
InBody R20 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 R20: when to consider it
R20 was developed for home body-composition monitoring and also appears in some fitness services. It gives a basic muscle-and-fat overview. For a more detailed consultation, it matters whether the provider also uses the computer report.
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.
