Is your body healthy? Just step on the scale to find out
The determining factors of physical health are body fat percentage and muscle mass. The Xiaomi Body Composition Scale S400 accurately measures body data, provides a detailed analysis of your physical condition, and identifies 'hidden factors' that contribute to the risk of obesity, thus aiding the scientific management of body shape and health.

Dual-frequency bioelectrical measurement
A new level of precision. Using high and low dual-frequency alternating currents that penetrate cell membranes, the electrical impedance values ​​of intracellular and extracellular fluids can be accurately measured, recording physical data such as body fat, water content, and muscle mass.

Professional and accurate body fat measurement
DEXA* is widely recognized in the industry as the basis for measuring body composition. The closer the correlation coefficient is to 1, the more accurate the measurement data. Compared to DEXA, the key data of the Xiaomi Body Composition Scale S400, such as body fat percentage and fat mass, have a correlation coefficient of 0.93*, ensuring a more accurate and reliable measurement.

Analysis of 25 body composition indicators / Complete control over your health
A single measurement generates an analysis report evaluating 25 body composition indicators, which includes your body composition, including body fat, muscle mass, water content, protein and bone density. It also assesses visceral fat levels and identifies hidden obesity risks. Get a comprehensive analysis of your health status, so you can quickly and easily identify changes.

Static pulse measurement / Heart health monitoring
A high or low heart rate can indicate a health problem. The Xiaomi Body Composition Scale S400 allows you to track your heart rate with a static heart rate measurement. Monitoring your heart health has never been easier.

Multiple measurement methods / One scale, multiple functions
You can quickly switch between modes using the Mi Home / Xiaomi Home app, such as baby weighing, balance testing, and allow guests to weigh.

Accurate and stable with longer battery life
A scale the whole family can trust. The large electrode pad increases the conductivity, making the measurements more accurate. The larger non-slip surface ensures stability, preventing the scale from tipping over. The battery only needs to be replaced every six months, so the whole family can enjoy a better user experience for longer.
