InBody 120 vs InBody 270S
InBody 120 and InBody 270S: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.
InBody 120: when to consider it
InBody120 is useful for following fat and muscle while changing your diet or activity. A meaningful consultation benefits from the full computer-generated report; the small display shows only part of the results.
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.

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.
