Nutriguard-MS vs Tanita RD-545HR
Nutriguard-MS 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.
Nutriguard-MS: when to consider it
Nutriguard-MS measures bioelectrical impedance at 5, 50 and 100 kHz. Standard testing uses four adhesive electrodes on the hand and foot of one side. Body-composition and water estimates are evaluated from resistance and reactance using the relevant software; regional mode requires the appropriate procedure.
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.
