Xiaomi Mijia Scale S400 Pro Square Black Electronic personal scale

Innovative display for richer data at a glance
Say goodbye to traditional LED screens. The 3.5" TFT colour display delivers high contrast, high brightness and precise colour reproduction, allowing more content to be displayed clearly.

Smarter interactive guidance simplifies every step
The TFT colour display provides smart, intuitive on-screen guidance to help you operate and use the scale correctly.

Advanced display content customisation
You can personalise the TFT display via the Xiaomi Home app and select data trends, adjust screen brightness, or configure other settings according to your needs.

Dual-frequency bioelectrical impedance measurement for more precision
Using 50kHz and 250kHz dual-frequency bioelectrical impedance technology, the scale accurately measures intracellular and extracellular fluid impedance values to record key metrics such as fat mass and body fat percentage. These readings are benchmarked against the industry gold standard DEXA with a correlation greater than 0.93.5,6

25 body composition indicators
Take better control of your health
Each measurement generates a customised body composition analysis report, providing detailed insights across 25 key metrics, including BMI, body fat percentage, fat mass and visceral fat level to give you a deeper understanding of your body condition.

Real-time body composition monitoring for healthier weight management
With the Xiaomi Home app, you can monitor trends in weight, body fat percentage, muscle mass and more in real time. Combined with standard weight recommendations, it provides more comprehensive data support for fat loss while reducing the health risks associated with excessive weight loss.

Suitable for all ages and all family members
The scale supports body composition measurements, including weight and body fat percentage, for users aged 6–80. It supports storage for up to 36 user profiles, so everyone in the family can track their health with ease.

Wide measurement range
Switch flexibly between weighing people and objects
With a weighing range of 0.1–150kg, the scale supports a variety of scenarios, including weighing small items, weighing while holding a baby, balance testing and guest measurements.

No electrode pads, just seamless innovation
300 × 300mm ITO-coated tempered glass replaces traditional electrode pads, expanding the measuring area from a limited section to nearly the entire scale surface, allowing it to accommodate different foot shapes and sizes comfortably (up to EU size 48).

Upgraded performance and long-lasting battery life
Even with the upgraded TFT colour display, battery life remains impressive. With 3 daily weigh-ins, it can last up to 150 days.12
