seca mBCA Alpha vs Tanita MC-780MA
seca mBCA Alpha and Tanita MC-780MA: compare documented specifications, features and limitations. Check the reports and explanation offered by the provider. More features alone do not establish better accuracy.
seca mBCA Alpha: when to consider it
mBCA Alpha is an eight-point BIA analyser using nine frequencies. Documentation lists a 24-second recording, 360 kg capacity and fat, skeletal-muscle mass and phase-angle outputs. The Alpha configuration contains the mBCA 554 platform and mBCA 545 handle.
Tanita MC-780MA: when to consider it
MC-780MA is a multi-frequency segmental BIA analyser. The manufacturer catalogue lists fat, muscle and body-water estimates with regional results and SD-card storage. MA alone still does not distinguish the column-mounted P and separate S configurations.

| Specifications | seca mBCA Alpha | Tanita MC-780MA |
|---|---|---|
| Method | Multi-frequency BIA | Multi-frequency BIA |
| Measurement frequencies | 1, 2, 5, 10, 20, 50, 100, 200, 500 kHz | Not verified |
| Maximum weight | 360 kg | Not verified |
| Recording time | 24 s; excluding preparation and consultation | Under 20 s; excluding preparation and consultation |

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.
