The Xiaomi Body Composition Scale S400 is the essential device for tracking and reaching your health and fitness targets. Forget basic weight tracking—this smart body fat scale provides professional health monitoring for you and your family, giving you highly accurate data you can trust.
Breakthrough Dual-Frequency Accuracy
The S400 uses advanced Dual-Frequency BIA (Bioelectrical Impedance Analysis) technology for superior precision. This system measures your body’s composition using two different electrical signals:
-
It checks the water inside your cells (High Frequency).
-
It checks the water outside your cells (Low Frequency).
This dual check ensures the data is exceptionally accurate, matching the high standards of clinical DEXA measurement ($\ge 0.93$ correlation). You get results you can rely on to guide your diet and exercise.
