Is your body healthy? Just step on the scale to find out
Physical health is determined by body fat percentage and muscle mass. Xiaomi Body Composition Scale S400 can accurately measure body data and provide a detailed analysis of your physical condition, identifying Ôhidden factorsÕ contributing to a risk of obesity to help scientifically manage your body shape and health.

Dual-frequency bioelectrical impedance measurement A new level of precision
Using high and low dual-frequency alternating currents to penetrate cell membranes, intracellular and extracellular fluids' electrical impedance values can be accurately measured to capture physical data such as body fat, water content, and muscle mass.
50kHz low frequency, Measure extracellular fluid, Measure water in blood and tissue fluids
250kHz high frequency, Measure intracellular fluid, Measure cellular components of muscle, fat, bones, and organs

Key data benchmarked against the industry gold standard, Professional and accurate body fat measurement
DEXA* is widely recognised as the industry gold standard for measuring body composition. The closer the correlation coefficient is to 1, the more accurate the measurement data indicates. Benchmarked against DEXA, Xiaomi Body Composition Scale S400 boasts a correlation coefficient of ³0.93* for key data such as body fat percentage and fat mass, ensuring more accurate and reliable data.

Analyse 25 body composition indicators
Take full control of your health
A single measurement can generate an analysis report of 25 body composition indicators* evaluating body composition including body fat, muscle mass, water content, protein, and bone mineral density. It also evaluates visceral fat rate and identifies hidden obesity risks. Get a deep analysis of your health status so you can quickly and easily identify any changes.

Cover more family members, Keep the whole family healthy*
With a fat measurement algorithm that can be calibrated for young people, the scale is suitable for all family members. Parents can quickly assess their children's health status and adjust their dietary and exercise schedules to make sure they maintain a healthy weight and body fat level and avoid the risks associated with obesity.
Store information for up to 36 family members*
Can be used from 6 to 80 years old

Static heart rate monitoring*
Focus on a healthy heart
A high or low heart rate could be a sign of a health issue. Xiaomi Body Composition Scale S400 lets you track your heart rate with static heart rate monitoring*. Keeping an eye on heart health has never been more convenient.

Multiple weighing modes

Accurate and stable with a longer battery life, A scale that the whole family can trust
The large-diameter electrode pad enhances contact conductivity efficiency for more accurate measurements. A larger anti-slip surface ensures stability to prevent the scale from tipping over. With a battery that only needs to be replaced every six months, the whole family can enjoy a better user experience for longer.

More interactive display, View key data at a glance
The body fat, heart rate and battery level are displayed directly on the scale for even more convenience. Open Mi Home/Xiaomi Home app at any time to view detailed reports for a clearer understanding of your health status.

Connect to Bluetooth¨ gateway for automatic synchronisation and instant access
The scale can be paired with and connected to your phone via a Bluetooth¨ gateway*. Measurement data will be automatically saved and uploaded to the server for convenient viewing anytime on the app.
