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 'hidden factors' 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.

 

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 =0.93* 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.

 

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 One scale, more functions

Quickly switch between modes using Mi Home/Xiaomi Home app* to Weighing with baby, or Balance testing, Visitor measurement, and allow guests to weigh themselves.

 

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.

Good Scale with Nice Features, But Not Perfect

I’ve been using the Xiaomi Smart Scale S400 for a while now. It looks great and feels solid. The app is easy to use and shows lots of details like weight, BMI, and body fat. It also connects quickly through Bluetooth, which is handy. The weight readings seem accurate, but the body fat and other numbers can change a bit each time you step on it. I think that’s normal for most smart scales, but if you want super precise measurements, this might not be the best choice. Compared to other scales I’ve tried, it’s about the same for accuracy but looks nicer. Overall, it’s a good scale for tracking your progress and has useful features for the price....view more

Excellent scales.

Simple and effective. Encourages you to use as you simply step on to get your morning readings. Don't need to turn on/off manually, or do anything other than step on to them.

Wrong demographic!

It’s a good product, but after I entered my personal details, it said it wouldn’t help me - I was too old! (I’m 82). So I lied about my age, and take its readings with a grain of salt. To be honest, I can’t really be bothered with all the statistical faffing about, but it’s good to record my weight day by day, and it’s a good-looking piece of kit. If you want to know your muscle-mass, fat percentage and so on, this is an affordable way to keep track.

Exactly what I was looking for

This scale is great; it provides so much useful information and is extremely easy to set up and use. Some information obviously isn't 100% correct but it's pretty hard to measure everything it offers with absolute certainty. For this price though it is perfect and I would highly recommend it!

Great Scale

Great but not perfect.
Works very well but can be a bit slow.
It's bare bones without using the Xiaomi app - which has lot's of good data about your health.
Looks nice for a scale - slimline & small footprint.
Hoping the battery life is good over time (3x AAA).
