Xiaomi Body Composition Scale S400 Smart Bathroom Scale

Dual-Frequency Bioelectrical Impedance Analysis (BIA)

The Xiaomi Body Composition Scale S400 uses advanced dual-frequency alternating current measurement to accurately penetrate both intracellular and extracellular fluids. By analyzing biological impedance across high and low frequencies, the scale captures comprehensive health metrics—including body fat percentage, muscle mass, total water content, and visceral fat—to reveal hidden obesity risk factors and support proactive physical wellness management.

DEXA Gold-Standard Measurement Precision

Calibrated against dual-energy X-ray absorptiometry (DEXA)—the recognized clinical gold standard in body composition analysis—the Xiaomi S400 achieves an industry-leading correlation coefficient of ≥0.93 for key metrics like body fat mass and percentage. This ensures lab-grade reliability and consistent measurement precision for tracking subtle body transformations over time.

Smart Health Monitoring and Body Shape Tracking

Designed for complete home health oversight, the smart scale provides in-depth physical health assessments every time you step on the platform. The detailed biometric data breaks down metabolic and physiological factors, empowering users to set achievable fitness targets, optimize dietary routines, and effectively track body recomposition progress.
