InBody BWA 2.0S vs Tanita BC-1000
InBody BWA 2.0S and Tanita BC-1000: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.
InBody BWA 2.0S: when to consider it
The newer BWA 2.0S combines detailed water results with composition and offers a shorter test than the original BWA. Testing can also take place while lying or seated. It is mainly intended for care where a professional follows water distribution and muscle quantity over time.
Tanita BC-1000: when to consider it
BC-1000 is a body-composition scale that transmits results wirelessly to a compatible receiver. Its manual lists fat, muscle and body water; capacity is 200 kg. BC-1000 Plus is a different version; accessories may vary in a package labelled “PROFI”.

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.
