The Xiaomi Body Composition Scale S400 is far more than a simple weight checker. Positioned as a “Health Data Manager,” it uses advanced technology to provide a detailed, multi-faceted picture of your body, going well beyond a simple number on a display. It’s a smart device designed to help you understand your health and manage it scientifically.

🧠 Smart Monitoring: The Core Technology

At its heart, the S400 uses Dual-Frequency Bioelectrical Impedance Analysis (BIA) technology. It sends two different alternating currents—a low-frequency (50kHz) and a high-frequency (250kHz)—through your body.

This allows it to accurately measure the impedance of both intracellular fluid (inside your cells) and extracellular fluid (outside your cells), providing precise data on critical metrics like body fat, muscle mass, and water content.

To give you even more confidence in its readings, the S400’s key data points, such as body fat percentage and fat mass, have been benchmarked against DEXA, the “gold standard” for body composition analysis.

The scale achieves a high correlation coefficient of ≥0.93 for these key metrics, ensuring professional-grade accuracy in your own home.

🎯 What It Can Measure: 25 Health Indicators

In just one step, the scale generates a comprehensive analysis report covering 25 essential health indicators. It assesses body fat, muscle mass, water content, protein, and bone mineral density, among other factors.

This in-depth report helps you identify potential health risks, like hidden obesity risks from visceral fat, and track subtle changes in your body. The detailed list of indicators includes:

  • Weight & BMI
  • Body Fat
  • Muscle Mass
  • Water Content
  • Visceral Fat
  • Bone Mass
  • Protein Levels
  • Basal Metabolic Rate (BMR)
  • Body Age
  • Heart Rate
