InBody 770S vs Tanita RD-545HR

InBody 770S 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 770S: when to consider it

A newer generation for nutrition and clinical follow-up with a detailed water report. Useful for discussing fat and muscle changes in the context of water distribution and phase angle, including individual body regions.

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.

Specifications side by side

The filter keeps rows with undocumented values. More features or a different value alone do not establish better measurement accuracy.

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.
