InBody R20 vs Tanita RD-545HR
InBody R20 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.
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 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.
