Tanita BC-545 vs Tanita RD-545HR
Tanita BC-545 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.
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.
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.
