InBody 120 vs OMRON BF511
InBody 120 and OMRON BF511: 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.
OMRON BF511: when to consider it
BF511 is a scale with eight sensors contacting hands and feet. It uses 50 kHz BIA to estimate body-fat percentage, skeletal-muscle percentage and visceral-fat level alongside weight and BMI. It provides a whole-body overview; separate limb results are not documented.
