Test how healthy your body is
Curious about your body's condition? Just step on the Xiaomi Body Composition Scale S400 body composition scale, and you'll instantly get a detailed picture of your physical state. The scale accurately records your body data, revealing the risk factors of hidden obesity, allowing you to scientifically and purposefully track your health progress.

Precise bioelectrical impedance measurement
The Xiaomi Body Composition Scale S400 uses dual-frequency bioelectrical impedance measurement, which elevates accuracy to a new level. With the help of alternating high and low-frequency currents, the scale provides accurate values for intra- and extracellular fluids. As a result, it reliably measures body fat percentage, water ratio, and muscle mass, among others.

The gold standard for body fat measurement
The Xiaomi Body Composition Scale S400 offers professional accuracy in body fat measurement. Its correlation coefficient is ≥0.93 for key data (such as body fat percentage, fat mass), which meets the industry gold standard of DEXA measurement. Thus, you can be sure that the results are authentic and accurate.

Analysis of 25 body composition indicators
The scale analyzes 25 different body composition indicators with a single measurement – including fat content, muscle mass, water balance, protein level, and bone density. It also evaluates the amount of visceral fat and recognizes hidden obesity risks. The detailed assessment helps you respond to changes in a timely manner.

For the whole family
Thanks to the measurement algorithm optimized for young people, the Xiaomi S400 scale is suitable for every family member. Parents can quickly check their children's body composition and adjust their diet or exercise program if necessary, thus preventing health problems related to obesity.

Heart rate monitoring
The Xiaomi Body Composition Scale S400 can measure resting heart rate. A heart rate that is too high or too low can be a sign of health problems, so it is important to monitor it. With the Xiaomi S400, monitoring your pulse can be done easily and conveniently.

Multifunctional measurement modes
The scale has several practical features: measuring small objects with 0.01 kg accuracy, baby and pet measurement mode, and guest mode, which does not save data. The measurement range is 0.1–150 kg. You can easily switch between different modes through the Mi Home / Xiaomi Home app.

Accuracy and stability with long battery life
The Xiaomi Body Composition Scale S400 features large electrodes for better conductivity and reliable measurement. The non-slip surface ensures safe use. The batteries only need to be replaced every six months, making the device comfortable to use in the long term.

Interactive display
On the scale's display, you can see the most important data, such as fat content, heart rate, battery level. The Mi Home / Xiaomi Home app provides detailed reports so you can get a complete picture of your health status.

Automatic synchronization and instant access
The scale can be paired with your phone via Bluetooth®. Measurements are automatically saved to the server, allowing you to conveniently review them in the app at any time.
