InBody 270S vs Tanita RD-545HR
InBody 270S 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 270S: when to consider it
InBody270S adds whole-body phase angle to routine fat-and-muscle tracking. It is useful if you want to discuss this extra measure in a consultation. Phase angle needs context from your condition and other results, rather than serving as a stand-alone health grade.
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.
