InBody R20 vs Tanita BC-545
InBody R20 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.
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.
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.
