InBody 270S vs InBody 520
InBody 270S and InBody 520: 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.
InBody 520: when to consider it
An older model for following fat, muscle and water during nutrition or exercise changes, and for understanding past results. Includes ECW/TBW and lean-mass distribution across the arms, legs and trunk.
